base-files: fix getting gid from group_add_next
Shell function return code only has range [0, 255]. Other values will
be truncated, e.g. return 65536 will have the same effect as return 0
While at it, drop other "return $rc" where rc will almost always take
value 0 and whose value current callers actually do not check
Fixes FS#988
