Alyssa Ross f34ee18635 mailmanPackages.postorius: use optional-dependencies
We have a mechanism for this — we don't need an overlay hack.

This overlay can be used whenever we need to override
dependencies specific to the mailman ecosystem: in the past
this was necessary for e.g. psycopg2[1] or sqlalchemy[2].
In such a large ecosystem this sort of issue is expected
to arise again. Since we don't want to clutter the python package-set
itself with version overrides and don't want to change the APIs
in here back and forth every time this comes up (and as a result
force users to change their code accordingly), this overlay
is kept on purpose, even when empty.
