[PATCH] build: dont use AC_CHECK_FILE when enabling DRI

Ross Burton ross.burton at intel.com

Automatically enabling or disabling a feature based on installed files isn't
deterministic, and AC_CHECK_FILE returns an error when cross-compiling.

Fix this by enabling DRI by default, and removing the explicit file checks as
pkg-config is good enough.

(#57606)
