util/nvmutil: use renameat for atomic writemkhtemp-wip

not rename(). use renameat()

this re-uses the logic added for mkhtemp.

this will later enable more stringent
integrity checks, though we already verify
the integrity of a file after writing it
back, and renameat is always tied to the
descriptor, so it's fine.
