object-file: fix SEGV on free() regression in v2.34.0-rc2
Fix a regression introduced in my 96e41f58fe1 (fsck: report invalid
object type-path combinations, 2021-10-01). When fsck-ing blobs larger
than core.bigFileThreshold, we'd free() a pointer to uninitialized
memory.
This issue would have been caught by SANITIZE=address, but since it
involves core.bigFileThreshold, none of the existing tests in our test
suite covered it.
Running them with the "big_file_threshold" in "environment.c" changed
to say "6" would have shown this failure, but let's add a dedicated
test for this scenario based on Han Xin's report[1].
The bug was introduced between v9 and v10[2] of the fsck series merged
in 061a21d36d8 (Merge branch 'ab/fsck-unexpected-type', 2021-10-25).
