Add NVIDIA_GL option to fix conflicts with Linux DRI

linux-c6/f10 metaports pull in their respective dri implementation, which
conflicts with nvidia-driver's libGL. Resolve this by adding an option for it,
and conditionally pull in either Linux DRI, or the NVIDIA driver.
Note: users of nvidia-driver will have to use ports for now.
