tests: persistent_group_profile_add to support P2P Device interface

Modify the persistent_group_profile_add test to support configurations
that use a dedicated P2P Device interface by sending the ADD_NETWORK and
SET_NETWORK commands on the global control interface and specifying the
P2P Device interface name.
