Move is_whitelisted to the common script so that all users get the previous fix

 # This script can be used to replace the "dpkg" binary as far as the
 # "apt-get install" command is concerned. When "apt-get install foo"
 # runs it will make two calls to dpkg like:
 #   dpkg --status-fd ## --unpack --auto-deconfigure /path/to/foo.deb
 #   dpkg --status-fd ## --configure foo
 # This script will extract the .deb file and make it appear to be installed
 # successfully. It will skip the maintainer scripts and configure steps.
 #
 # As a one-off test, you can run like:
 #  apt-get -o="Dir::Bin::dpkg=/path/to/this" install foo
 
 # Load common constants.  This should be the first executable line.
 # The path to common.sh should be relative to your script's location.
