[cairo] [PATCH] Missed a DRM header when making a distribution.

[Daniel Mierswa]

This will add a missing a header to the list of installed header files
when 'make dist' is invoked. The current 1.9.4 snapshot misses that one.

If you still don't like it, that's ok: that's why I'm boss. I simply
know better than you do.
