tests: Make scan_for_auth more robust

Browse Source 
It was apparently possible for this test case not to do what it was
supposed to do, i.e., get nl80211 Authenticate command failing due to
cfg80211 BS entry missing. With the external radio work blocking fixed,
this can be cleaned up by explicitly waiting for the scan event. In
addition, a less used channel can be selected to avoid finding other BSS
entries.
