xserver-xorg: report DRI3 and Present modules as present

The DRI3 and Present modules are built-in but some drivers (such as
xf86-video-intel) want to query their presence.  Backport a patch from upstream
to stop this causing an error.

+
+This is so that drivers can do a runtime check that DRI3 is available,
+similar to existing runtime checks performed by the drivers for DRI and
+DRI2.
+
+v2: Only add DRI3 to the list if the module was actually built into the
+server (Mark Kettenis).
