Create the temporary files needed for tests

Rather than keeping test input files in git, create them on the fly as
needed. This allows us to streamline one or two tests that modify the
files and then try to restore their old contents, and it also ensures
that looking at a given test it is clear which files are really being
used.

This change also updates the implementation of some tests that were
counting log calls to see how many files were loaded by making the
Enforcer track the files it loads so we can look at the list explicitly.
This gives us verification that the files we care about are the ones
being loaded, and is less brittle in case we change the logging
structure within the policy module.
