[0/3] Add GIT_TEST_MULTI_PACK_INDEX environment variable

Message

To increase coverage of the multi-pack-index feature, add a
GIT_TEST_MULTI_PACK_INDEX environment variable similar to other GIT_TEST_*
variables.

After creating the environment variable and running the test suite with it
enabled, I found a few bugs in the multi-pack-index implementation. These
are handled by the first two patches.

I have set up a CI build on Azure Pipelines [1] that runs the test suite
with a few optional features enabled, including GIT_TEST_MULTI_PACK_INDEX
and GIT_TEST_COMMIT_GRAPH. I'll use this to watch the features and ensure
they work well with the rest of the ongoing work. Eventually, we can add
these variables to the Travis CI scripts.
