issue2551167 - update wheel support.
New method for finding locale and template files when installed as
a wheel. It acts more like existing code for egg support.
Add build-arg source=local_pip for building using pip using the local
files rather than downloading from pypi. Useful for testing these
changes. Since it's developer testing code and still has the downside
that man pages aren't accessible, I am not documenting it as an
option.
