logilab-astng #50205 avoid double parsing of modules [open]

When using implicite relative import or running pylint from a package like:

logilab/ $ pylint astng/

astng will generate the same module with different name like 'astng.builder' and 'logilab.astng.builder. We should use Module.file to avoid that, but what is the "right" name of the module.
