Thiago Macieira d55db285fc Autotest: Fix a race condition in launching the QtDBus sub-processes
Wait for the subprocess to print "ready" before assuming that it is
ready to receive calls. waitForStarted() will return as soon as the
child is running, but it may not have registered on D-Bus yet.

This also solves the synchronization problem more elegantly than how
tst_qdbusmarshall.cpp was trying to do it.
