rev-list: disable --use-bitmap-index when pruning commits
The reachability bitmaps do not have enough information to tell us which commits might have changed path "foo", so the current code produces wrong answers for: git rev-list --use-bitmap-index --count HEAD -- foo (it silently ignores the "foo" limiter). Instead, we should fall back to doing a normal traversal (it is OK to fall back rather than complain, because --use-bitmap-index is a pure optimization, and might not kick in for other reasons, such as there being no bitmaps in the repository).
