[arch-dev-public] Move the catalyst drivers from extra to AUR/Community

[Eduardo Romero]

Yeah, I tried to find a solution of how to work this out and keep catalyst
at least in community, but it seems, ATI/AMD just aren't doing a thing to
improve the situation. Yet, this package is so important for some users of
Arch Linux that a TU should be the one in charge of them.
