Dropped LFS3_YES_* variants of traversal/gc flags

Previously these only implied M/F flags, which risks quite a bit of
confusion. It's entirely reasonable to expect these to affect lfs3_fs_gc
(arguably the more correct behavior?) but they did not.

Maybe these should imply the GC behavior, or maybe we should rename them
to LFS3_YES_GC_*/LFS3_YES_M_*/etc, but at the very least the current
behavior of implying M/F is probably not a good idea.

So, removing for now. This is the safest option, and better thought-out
behavior can be added in the future.
