rev-list: disable --use-bitmap-index when pruning commitsjk/rev-list-no-bitmap-while-pruning

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).
