qemuxmlconftest: Include shared memory 'net-vhostuser' test cases

The vhost-user protocol requires shared memory support to work properly.

Our test XMLs didn't have it configured as for interface the check if
shared memory is present only produces a warning instead of a proper
error.

Upcoming patches will be moving the check to become fatal so the test
cases need to be fixed first.
