Subject: [PATCH 1/2] Use gethostname instead of g_get_host_name in greeter

The latter is unreliable when the hostname changes at runtime.

Subject: [PATCH 2/2] Don't bother showing hostname if it's not unique

The advantage of showing hostname by default is it is a
unique identifier for people who have multiple machines.

If it only says "localhost" or "localhost.localdomain"
that advantage is mitigated, and it's probably better to
show OS release.
