x11-drivers/xf86-video-virtualbox: build vboxdrv.ko objects a little differently

This is an attempt at preventing bug 582078.  With DRM_TTM enabled in the kernel
(choosing the DRM module for any of the other VMs will include it), and a sufficient
vmalloc= specified to the kernel (at least 1.5x the amount of gpu memory provided), the module
will load into the kernel.

Tests on an x86 vm and 4.1.23 kernel resulted in PANICs; YMMV.

Package-Manager: portage-2.2.26
