tests: Support P2P group interfaces in hwsim remote tests

Start using the wpa_supplicant remote UDP interface for the control and
monitor sockets for P2P group interfaces so that P2P tests would work on
real hardware. Also have the group requests and events show in the test
log with the hostname and the interface name of the group interface.
