python,python3: add host python pip install support

To install Python packages host side, that
may be needed for a build.

The intent, is to try to reduce host-side Python
packages being installed via LEDE/OpenWrt build system.
Because those seem like a pain to maintain.

The idea is adapted from Yousong's `python-packages`
package.
