GConf makes its own CORBA connection if it needs to, and
the only reason we included orbit.h is to check whether
the problematic version < 2.8 was present, as it deadlocks
the GTK VCL plugin.

But ORbit 2.8 was released in 2003, and GConf doesn't
even use CORBA connections any more. So drop the check
and stop needing ORBit altogether.
