The CI was sometimes taking ~10-15 minutes to run just this
test. This is likely due to the test having 7 radios and
which is a lot of beacons/probes to process.
Disabling the unused hostapd instances drops the runtime down
to about 1 minute.
This was copy pasted from the autoconnect test, and depending on
how the python module cache is ordered can incorrectly use the
wrong test class. This should nothappen because we insert
the paths to the head of the list but for consistency the class
should be named something that reflects what the test is doing.
