libdrm: don't detect components that have been disabled

We pass --disable-cairo-tests but if cairo is in the sysroot it is detected and
used, which causes problems in mass builds as cairo could be removed whilst
libdrm is being built.

+    Currently with --disable-amdgpu --disable-valgrind --disable-cairo-tests
+    cunit, valgrind and cairo are still detected.
