Gregory Haynes 6278371eaa Make dib-python use the default python for distro
Right now dib-python works by trying to find any python on a system in
an order of precedence. A much better way is if we are explicit about
the python we intend to be there which will allow us to make better
decisions in other elements (such as allowing for package-installs to
take into account DIB_PYTHON_VERSION) as well as allow for users to
specify a preferred python version.
