qemuBuildPanicCommandLine: Generate via JSON

Browse Source 
Format a JSON object with the device properties and then use
qemuBuildDeviceCommandlineFromJSON to convert it to the standard
commandline for now.

The 'ioport' property of 'pvpanic' is a number in QEMU:
  ioport=<uint16>        -  (default: 1285)
