test_driver: implement virDomainSendProcessSignal

Only succeed when @pid_value is 1, since according to the docs this is
the minimum requirement for any driver to implement this API.
Since this is test driver, we assume that any signal from the supported
list can be sent to pid 1 and we therefore succeed every time.
