Two years ago, commit ff1e653c8e2 (midx: respect 'GIT_TEST_MULTI_PACK_INDEX_WRITE_BITMAP', 2021-08-31) introduced a new environment variable which caused the test suite to write MIDX bitmaps after any 'git repack' invocation. At the time, this was done to help flush out any bugs with MIDX bitmaps that weren't explicitly covered in the t5326-multi-pack-bitmap.sh script. Two years later, that flag has served us well and is no longer providing meaningful coverage, as the script in t5326 has matured substantially and covers many more interesting cases than it did back when ff1e653c8e2 was originally written. Remove the 'GIT_TEST_MULTI_PACK_INDEX_WRITE_BITMAP' environment variable as it is no longer serving a useful purpose. More importantly, removing this variable clears the way for us to introduce a new one to help similarly flush out bugs related to incremental MIDX chains. Because these incremental MIDX chains are (for now) incompatible with MIDX bitmaps, we cannot have both.
