HS 2.0R2: Fix permissions for SP/<fqdn> directory on Android

Browse source 
As part of OSU, the AAA TrustRoot cert is downloaded into SP/<fqdn>
directory. On Android, wpa_supplicant runs with Wifi uid privileges, and
hence might not have read access to the AAA TrustRoot present SP/<fqdn>
directory. Hence, make AID_WIFI as the group owner of SP/<fqdn>
directory and allow the members of AID_WIFI group to read files present
in this directory.
