libgdm: filter out sessions with duplicate names

Right now if two session files have the same translated name, the login
screen will show both of them.  There's no way the user can know which
session does which, so that's not a great user experience. Furthermore,
in the face of symlinks, both sessions truely could be identical.

This commit filters out the duplicates, so only one shows in the list.
