Martin Flöser 825aa4ac38 [platform/virtual] Drop support for vgem and rendernode
Summary:
Instead we depend on the surfaceless platform for which we recently
added support. Thus the plugin does not need to use gbm and udev
anymore. So simplifies a lot.

Test Plan: ctest (prior to breaking change) passes
