tests: qmp-test: add oob test 

Test the new OOB capability.  Here we used the new "x-oob-test" command.
First, we send a lock=true and oob=false command to hang the main
thread.  Then send another lock=false and oob=true command (which will
be run inside parser this time) to free that hanged command.
