pip_install_wheel: add a generic do_install for bootstrapping

Several recipes are duplicating the same bootstrap logic for installing
a wheel without using any tools.  Add an implementation to
pip_install_wheel to centralise the code, and remove the duplicated code
from the following recipes:

- python3-flit-core
- python3-pip
- python3-setuptools
- python3-wheel
