conman:  Fake all subprocesses consistently.

conman unit tests currently fake subprocess calls in a variety of ad
hoc methods.

This adds a fake subprocess module that delegates subprocess calls to
fake Python implementations.  This made it possible to rewrite the
conman unit tests to be much more consistent, organized, and bug-free.

This rewrite uncovered some small bugs (all changes to non-test files
comprise the resulting fixes, or related cleanup).
