libdrm: Add --disable-cairo-tests switch and update to upstream patch

Rather than implicitly relying on Cairo being disabled through not being
present, add a configure switch to forcibly disable it.

The updates the code to use a patch backported from upstream git
instead of our custom version.

+    configure.ac: Allow forcible disabling of Cairo support
+    
+    We don't want to build libdrm tests with Cairo support under Poky, since
+    they're never used and also cause a build loop from libdrm -> cairo ->
+    mesa-dri -> libdrm.
+    
+    To avoid variance in build results, introduce a --disable-cairo-tests
+    switch.

-isn't good enough. If its not in DEPENDS, it can disappear half way through building.
-We therefore need to explictly disable it.
