hostname: -s: do not look up details via dns

This changes the hostname behavior to match other systems and its own
documentation.  Namely, that -s just parses the result of the active
gethostname() and does not attempt any network/DNS traffic.  Other
distros like Fedora/RedHat and Debian/Ubuntu have also changed their
behavior in this regard.
