George Hartzell 8ab69c4d32 Update R&friends to use our X11 libs (#2053)
* Update R&friends to use our X11 libs

Add `depends_on()`'s for R, Cairo, and Tk so that they use the Spack X
bits.

* Conditionalize X stuff on variant

Another step towards hooking up the X stuff.

There's still discussion happening on the issue, but this is better
than the 'everything must build with X' state that it was in.
