setting to completely override server hostname

Labs has instances hostnames forged in sequences which make them not
that much useful for human readable output. Labs does publish a
meaningful instance name as an env variable though, so we could use it
to get better output.

This patch introduce $wgOverrideHostname (default false) which when
set will override the hostname returned by wfHostname().
