[COOK-2952] chef-client cookbook has foodcritic failures
fix syntax error in conditional
add apt to berksfile for kitchen
add config to service init suite

We need to ensure that the configuration file exists so that init
scripts that check for its existence (EL family in particular) don't
cause an exception (return code 6 on service startup)
/usr/local/bin isn't in the default path
need to add config recipe for cook-1951 too
