qemu: add QEMU_CAPS_MACHINE_VMPORT_OPT

Browse Source 
Set the capability based on qmp query, or qemu version.  The qmp query
includes vmport with 2.2, but no longer with 2.3. It lists only
non-machine specific capabilities, so check the qemu version too until a
machine-specific query is supported.
