util/nvmutil: use real rename() syscall

i was being cute earlier, but the rewrite
defeats the purpose of atomic file handling
in nvmutil, by not actually renaming! it was
more like, doing an actual copy, which meant
that corruption is likely during power loss

i've commented the code because i may
use it in a library in the future.
