scripts: set timeout when waiting for qemu monitor connection

Browse source 
If QEMU fails to launch for some reason, the QEMUMonitorProtocol
class accept() method will wait forever in a socket accept call.
Set a timeout of 15 seconds so that we fail more gracefully
instead of hanging the test script forever
