[PATCH 4/7] python/qemu: Add pipenv support

[John Snow]

pipenv is a tool used for managing virtual environments with precisely
specified dependencies. It is separate from the dependencies listed in
setup.py, which are (by 'best practices') not supposed to be pinned.

Note that pipenv is not required to install or use this module; this is
just a convenience for in-tree developing.

Here, a "blank" pipfile is added with no dependencies, but specifies
Python 3.6 for the virtual environment.

Pipfile will specify our version minimums, while Pipfile.lock specifies
an exact loudout of packages that were known to operate correctly. This
latter file provides the real value for easy setup of container images
and CI environments.
