virtio-gpu: build modular 

Only build virtio-gpu-device modular (the code which actually depends on
the external virglrenderer library).  virtio-gpu-pci and virtio-vga are
compiled into core qemu still.

# FIXME: this was attempted in the Makefile build system; it was then reverted
# as it would try to load all devices when the module is loaded, even if
# config_devices for this target only has some of them. Since virtio-gpu-pci
# and virtio-vga both instantiate a virtio-gpu-device, fixing it probably does
# not even require a dependency system, just splitting the module in three
# for CONFIG_VIRTIO_GPU/CONFIG_VHOST_USER_GPU, CONFIG_VIRTIO_PCI and
# CONFIG_VIRTIO_VGA/CONFIG_VHOST_USER_VGA.
# Sourcesets are a dime a dozen, so keep it and just disable module builds.
