Added support for all mount-traversal flags in lfs3_format

Browse Source 
I mean, why not? These redirect to the same internal lfs3_fs_gc_
function anyways. Might as well keep things consistent.

Added:

  LFS3_F_MKCONSISTENT  0x00000800  Make the filesystem consistent
  LFS3_F_RELOOKAHEAD   0x00001000  Repopulate lookahead buffer

LFS3_F_MKCONSISTENT is guaranteed to be a noop, but LFS3_F_RELOOKAHEAD
forces a filesystem traversal, which may have some niche use case.

No code changes.
