util: remove lookup_uid(), replace by uid_to_name()
So far we had two pretty much identical calls in user-util.[ch]: lookup_uid() and uid_to_name(). Get rid of the former, in favour of the latter, and while we are at it, rewrite it, to use getpwuid_r() correctly, inside an allocation loop, as POSIX intended.
