Dominique Leuenberger 5a66372deb datetime: Allow changing the timezone if polkit says so 
As changing the time can have security implications, such as expiring
passwords, while changing the timezone doesn't, it's not unusual to
have a setup where org.freedesktop.timedate1.set-timezone is allowed
while other time-related actions aren't.

Therefore, if org.freedesktop.timedate1.set-timezone is allowed, there's
no reason to require that the user unlocks the panel to enable them to
change the timezone.
