diagnostic: commonize the building of diagnostic dict

Browse Source 
AP mode will use the same structure for its diagnostic interface
and mostly the same dictionary keys. Apart from ConnectedBss and
Address being different, the remainder are the same so the
diagnostic_station_info to DBus dictionary conversion has been made
common so both station and AP can use it to build its diagnostic
dictionaries.
