xfree86: os-support: fix FTBS when no recent enough libdrm found 

On Linux, the only supported platform bus backend (*1) is via DRM/DRI.
Trying to build it w/o (recent enough) libdrm fails as it tries to
compile the drm-based implementation, w/o having drm.h available. (*2)

In order to fix this, we need to compile noop-implementation instead.

*1) platform specific code for detecting video devices
*2) https://gitlab.freedesktop.org/xorg/xserver/-/issues/1771
