Test P2PS GO and CLI discoverability on group operating channel.
In order to implement these tests, refactor p2ps_connect_p2ps_method
and test_p2ps_connect_adv_go_pin_method to reuse the code for
connection establishment. Also change p2ps_exact_seek so it will
allow getting Probe Response frames from several peers.
