[Intel-gfx] [PATCH] configure: Use proper variables set by PKG_CHECK_MODULES

[Rémi Cardona]

$DRI_CFLAGS does not actually exist. The PKG_CHECK_MODULES call creates
a $DRI1_CFLAGS variable instead. This doesn't break often because
"recent" versions of xorg-server.pc indirectly depend on xf86driproto.pc
thus bringing in the required CFLAGS through $XORG_CFLAGS.
