automation: add x86_64 test (linux argo)

Add x86_64 hardware test that creates a Xen Argo communication
connection between two PVH domains. In the test, dom0 creates a domU and
listens for messages sent by the domU through Argo.

To accomplish this, build Xen with CONFIG_ARGO=y and create a CI test job.

Update the xilinx x86_64 test script to support the new test, and add
"sync_console" to command line to avoid an issue with console messages
being lost.
