Subject: fix return value of gethostnbyname[2]_r on result not found

these functions are horribly underspecified, inconsistent between
historical systems, and should never have been included. however, the
signatures we have match the glibc ones, and the glibc behavior is to
treat NxDomain and NODATA results as a success condition, not an
ENOENT error.
