Bugzilla Bug 123148

I emerged quake3-bin with USE="cdinstall", everything went fine until I tried
to run the game:

You also need to install quake3-data with USE=cdinstall.

This is INVALID, but I am adding a check to quake3-bin to force usage of
cdinstall on quake3-data if it is enabled in quake3-bin, so it is also FIXED. 
:P
