lorry.{g,}zip-importer: Only import modules and classes into module scope

Currently these scripts import a bunch of functions into module scope,
which is a bit confusing.  Change them to access functions through their
enclosing module names.

In lorry.gzip-importer, hexversion and stderr weren't used at all.
