unit: add test for band fallback

Browse Source 
This test uses the same country/country3 values seen by an AP vendor
which causes issues with IWD. The alpha2 is ES (Spain) and the 3rd
byte is 4, indicating to use the E-4. The issue then comes when the
neighbor report claims the BSS is under operating class 3 which is
not part of E-4.

With the fallback implemented, this test will pass since it will
try and lookup only on ES (the EU table) which operating class 3 is
part of.
