[PATCH 2/9] tests: Remote hwsim tests skip broadcast connectivity test

[Jonathan Afek]

The regular hwsim tests use both unicast and broadcast frames to test
the connectivity between 2 interfaces.
For real hardware (remote hwsim tests) the broadcast frames will
sometimes not be seen by all connected stations since they can be in
low power mode during DTIM or because broadcast frames are not
acked.
This commit makes the connectivity test for real hardware use
only unicast frames instead of both unicast and broadcast.
