Currently, virgl support has to go through a local unix socket, trying
to connect to a VM using -spice gl through spice://localhost:5900 will
only result in a black screen.
This commit errors out when the user tries to start a VM with both GL
support and a port/tls-port set.
This would fit better in spice-server, but currently QEMU does not call
into spice-server when parsing 'gl' on its command line, so we have to
do this check in QEMU instead.
