xf86-video-vmware: respect opengl DISTRO_FEATURE

Conditionalise the GL dependencies on the opengl DISTRO_FEATURE so this driver
can build without the opengl feature active, as the configure script will
enable/disable the GL sub-driver depending on the presence of these libraries.

This is an interim patch to fix the autobuilder, a more complete patch heading
upstream to make the GL sub-driver deterministic will follow.
