[wpa_supplicant] Enable RCOI selection for Passpoint

Enable the flow of adding RCOI selection IE in the (re)association
frames. Android does not use the native HS 2.0 support in
wpa_supplicant, so added logic to skip this check in Android
builds.

Bug: 210879633
Test: Verify function is called, succesful connection to Passpoint
network with RCOI match.
