[PATCH v2] t1501: fix test with split index

[Thomas Gummerer <t.gummerer@gmail.com>]

t1501-worktree.sh does not copy the shared index in the "relative
$GIT_WORK_TREE and git subprocesses" test, which makes the test fail
when GIT_TEST_SPLIT_INDEX is set.  Copy the shared index as well in
order to fix this.

Yeah that makes sense, thanks.
