[OE-core] [PATCH] xf86-video-omap: don't use AC_CHECK_FILE

[Ross Burton]

Upstream uses AC_CHECK_FILE to find dri.h, but that errors out when
cross-compiling.  Until oe-core 1b0d9cb1801a8eb68c82dfcda5a1da420ac8dd83 this
wasn't a problem because we patched AC_CHECK_FILE to always pass, which was a
nasty hack.

Patch configure.ac to use pkg-config like it should, and not AC_CHECK_FILE.

+Subject: [PATCH] build: rationalise DRI checks
+
+The existing logic around DRI was complicated and defined a number of variables
+that were not used, when in reality DRI is required.
+
+Move the glproto check to the main pkg-config check, and remove everything else.
