Looks good to me overall, but the commit log and comments seem not so
clear to me :)
Some comments inline.

I think this is because newer version of xfsprogs doesn't allow
specifying an option multiple times.

Need more comments to state that ATTR2 and LAZYSBCOUNT are features we
want to keep, otherwise this looks like only these two features are
cleared.

I'd keep above two requires to make sure mkfs supports such features.

What does this _scratch_mkfs do?
