As a suggestion for an alternative approach, instead of specifying both
the variable name and its value on the CLI we could add support for
appending values to $environment_filter, ie: specify which variables
should be whitelisted.

Something like:
  --allow-var=FOO --allow-var=BAR

Resulting in:
  $environment_filter = [Dpkg::BuildInfo::get_build_env_allowed(), 'FOO', 
'BAR'];

Either way, definitely a useful feature!
