There were no tests checking for the output of the git_die_config()
function in the config API, added in 5a80e97c827 (config: add
`git_die_config()` to the config-set API, 2014-08-07). We only tested
"test_must_fail", but didn't assert the output.

Let's check for that by extending the existing tests, and adding a new
one for "fetch.negotiationAlgorithm" so that we have a test for a user
of git_config_get_string*() calling git_die_config().

The other ones are testing:

- For *-resolve.sh: A custom call to git_die_config(), or via
  git_config_get_notes_strategy()
- For *-prune.sh: A call via git_config_get_expiry().

We also cover both the "from command-line config" and "in file..at
line" cases here.

The clobbering of existing ".git/config" files here is so that we're
not implicitly testing the line count of the default config.

It wasn't immediately obvious to me why this was relevant to this
series; but reading ahead to 5/9 shows that git_die_config() is a caller
of a *_get_value_multi() function that we are changing, so we want to
assert on the output so that we know that git_die_config() is still
doing the right thing (since test_must_fail alone won't tell us whether
we introduced bugs in git_die_config()).

Might be good to include that extra context, but I don't feel strongly
about it.
