auto-t: fix testAPRoam

This test occationally fails due to no hwsim rules. Basically we
were just expecting iwd to connect to one of 3 access points but
the ranking was equal, so it chose the first in the scan list.

Now a signal strength is assigned to each AP to steer IWD into
connecting to the expected AP.
