python3: add 'ensurepip' to python3-pip sub-package

Fixes:
  https://github.com/openwrt/packages/issues/12707

Seems to work.
Looking into the 'venv' lib, it seems it's installing pip & setuptools
inside a virtual environment.

`python3-pip` is already ~6 MB.
This adds another ~3 MB.

But, this gives users the ability to run Python virtual environments, which
is a pretty common feature of Python in production cases (usually web
stuff).
