Alberto Garcia a5df73baaf qtest.py: Wait for the result of qtest commands 
The cmd() method of the QEMUQtestProtocol class sends a qtest command
to QEMU but doesn't wait for the return message ("OK", "FAIL", "ERR").
Because of this, it can return control to the caller before the
command has actually finished.

In cases like clock_step or clock_set this means that cmd() can return
before all the timers triggered by the clock change have been fired.
This can be fixed by making cmd() wait for the output of the qtest
command.

This fixes iotests 093 and 136, which are flaky since commit
8258292e18 when the machine is under heavy workload.
