auto-t: make spoof_frame more robust

Browse Source 
Sometimes scan results can come in with a MAC address which
should be in the first index of addrs[] (42:xx:xx:xx:xx:xx).
This causes a failure to lookup the radio path.

There was also a failure path added if the radio cannot be
found rather than rely on DBus to fail with a None path.

The arguments to SendFrame were also changed to use the
ByteArray DBus type rather than python's internal bytearray.
This shouldn't have any effect, but its more consistent with
how DBus arguments should be used.
