The argument for this flag is pretty brittle. Yes it's _technically_
possible to end up with a compactable filesystem during lfsr_format, but
it's pretty unlikely. And keeping LFS_F_COMPACT around means we'd always
need the lfsr_mtree_gc circuitry in lfsr_format, for such a niche
situation, that can be easily cleaned up in lfsr_mount.
So dropping for now.
No code changes, but this does mean one less feature to support:
code stack ctx
before: 37804 2608 620
after: 37804 (+0.0%) 2608 (+0.0%) 620 (+0.0%)
