pycompat: alias urllib symbols directly

urllib.request imports a bunch of symbols from other urllib
modules. We should map to the original symbols not the
re-exported ones because this is more correct. Also, it
will prevent an import of urllib.request if only one of
the lower-level symbols/modules is needed.
