tests: Add qemu-guest-agent system test.
Enable the QEMU guest agent interface in marionette VMs, run the qemu-guest-agent service in one and try talking to it. * gnu/build/marionette.scm (make-marionette): Enable the guest agent device. * gnu/tests/virtualization.scm (run-qemu-guest-agent-test): New procedure. (%test-qemu-guest-agent): New variable. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
