The two JGit tests 'we can read jgit bitmaps' and 'jgit can read our
bitmaps' in 't5310-pack-bitmaps.sh' fail when run with
GIT_TEST_SPLIT_INDEX=YesPlease. Both tests create a clone of the test
repository to check bitmap interoperability with JGit. With split
indexes enabled the index in the clone repositories contains the
'link' extension, which JGit doesn't support and, consequently, an
exception aborts it:
<...>
org.eclipse.jgit.api.errors.JGitInternalException: DIRC extension 'link' not supported by this version.
at org.eclipse.jgit.dircache.DirCache.readFrom(DirCache.java:562)
<...>
Since testing bitmaps doesn't need a worktree in the first place,
let's just create bare clones for the two JGit tests, so the cloned
won't have an index, and these two tests can be executed even with
split index enabled.

Since testing bitmaps doesn't need a worktree in the first place,
let's just create bare clones for the two JGit tests, so the cloned
won't have an index, and these two tests can be executed even with
split index enabled.
Nice, this seems like a clever workaround.

The more heavy-handed approach would be to just disable the JGIT prereq
when GIT_TEST_SPLIT_INDEX is in use, which would cover this and
potentially any other cases. This is nicer because it lets us continue
using the test. And it's not like we have a ton of jgit dependencies,
such that dealing with each individually would be a burden.

We could also 'sane_unset GIT_TEST_SPLIT_INDEX' in these two tests,
but I think that we should do that only in tests that specifically
check split index behavior (i.e. t1700).
