x11/xf86-video-vmware: Enable xatracker by default if X11_TYPE == modular

libxatracker is required for making use of DRM/KMS and its 3D acceleration
capability. It's a part of Mesa but isn't guaranteed to be built, e.g. the
native Mesa in NetBSD doesn't provide it.

Also enable udev support on Linux by default. It's seemingly used for
monitor hot-plugging.
