this may be improved in the future

- fix naming within util.lua
- break if autoupdater was executed without errors
- use dual-stack interface

ffho-autoupdater-wifi-fallback: let get_available_wifi_networks() return a table of possible wifi networks

If there is a hidden network in range it will have a 'nil' SSID value and the match function will result in an error aborting the updater.
This commit also checks for the bssid value so that if the bssid gathering whyever fails it doesn't let the whole updater fail.
