migrate: replace RMP_ flags with TTU_ flags
Instead of translating between RMP_ and TTU_ flags, remove the RMP_ flags
and just use the TTU_ flag space; there's plenty available.
Possibly we should rename these to RMAP_ flags, and maybe even pass them
in through rmap_walk_arg, but that can be done later.
