Add tests for "git worktree list" verbose mode, prunable and locked
annotations for both default and porcelain format and ensure the
"prunable" annotation is consistent with what "git worktree prune"
command will eventually remove. Additionally, add one test case to
ensure any newline characters are escaped from locked reason for the
porcelain format to prevent breaking the format.

The c57b3367be (worktree: teach `list` to annotate locked worktree,
2020-10-11) introduced a new test to ensure locked worktrees are listed
with "locked" annotation. However, the test does not remove the worktree
as the "git worktree prune" is not going to remove any locked worktrees.
Let's fix that by unlocking the worktree before the "prune" command.

You might need to be a bit more careful here. If the test fails before
the worktree is locked, then the `git worktree unlock` in the cleanup
code will return an error, which will make the code executed by
test_when_finished() fail, as well, which makes it harder to debug
problems. Moving the `unlock` cleanup after you know the lock
succeeded will address this issue:

    test_when_finished "rm -rf locked unlocked out && git worktree prune" &&
    git worktree add --detach locked master &&
    git worktree add --detach unlocked master &&
    git worktree lock locked &&
    test_when_finished "git worktree unlock locked" &&
    ...

Same comment applies to other new tests added by this patch which lock
worktrees.

To be trustworthy, doesn't this test also need to have an unprunable
worktree, and test that `git worktree list` doesn't annotate it as
"prunable" _and_ that `git worktree prune` didn't prune it? Otherwise,
we really don't know that the two commands agree about what is and is
not prunable -- we only know they agree that this particular worktree
was prunable.

Nit: It's not a big deal, but we don't normally bother cleaning up
every junk file in tests, such as `out`, `actual`, `expect` if those
files aren't going to be a problem for subsequent tests. We are
explicitly cleaning up the worktrees in these tests because this
script is all about testing worktree behavior, and some random
leftover worktree could be a problem for other tests. I don't care
strongly one way or the other, but I worry a tiny bit that the list of
files being cleaned up could become outdated as changes are made to
the tests later...

... for instance, the file `list` being cleaned up in this test is not
even created by this test.

Nit: This test title could probably be shortened to:

    '"list' --verbose and --porcelain mutually exclusive' '

Finally, I haven't tried it myself, but I was wondering if it is
possible to make a test which shows both "locked" and "prunable"
annotations for the same worktree. Would that be possible by
specifying a particular value for `--expire`? If it's too much work,
don't worry about it.

Ignore this stupid question/suggestion. A locked worktree will never
be considered prunable. Don't know what I was thinking when I asked
it.

This is good point. will change on the next revision.

You're right this test is missing the case the "unprunable case". Will
add into the next revision.

Make sense, and ...

This is exactly the case of updating the test and forgetting to
remove from the cleanup part because it was not used anymore. I'm also
inclined to make this changes on the next revision.
