marionette: Use QEMU's "VM channel" mechanism. 

* gnu/tests.scm (<marionette-configuration>)[device]: Default to
"/dev/virtio-ports/org.gnu.guix.port.0".
* gnu/tests.scm (marionette-shepherd-service): Remove (guix build
syscalls) from 'modules'.  Remove 'tcsetattr' call from 'start'.
* gnu/build/marionette.scm (make-marionette): Use "-virtserialport"
instead of "-virtconsole".
