find_dpkg_trigger_cycles.sh: use APT_CONFIG environment variable instead of commandline option

 - using commandline options does not work reliably because commandline
   options are parsed last and thus many settings will not take effect
 - see apt.conf(5) for the order in which configuration file parameters
   are parsed by apt
