python3: merge python3-email into python3-urllib

As we're seeing in various test.sh scrip runs, importing 'email' fails
with not finding 'urllib' and vice-versa.

Then via a7e96ec91 ("python3-email: add python3-urllib as dependency")
I created a circular dependency.
So, might as well merge the two packages into one (named python3-urllib)
and updates all dependencies to pull python3-urllib.
