tests: run the whole hg-core/path_auditor test in a clean temp dir

This makes the whole test happen in a clean temporary directory in
`$TMPDIR/$random`, and simplifies the test a bit by eliminating unnecessarily
dynamic path elements computations.

Before this patch, the first part of the test was happening in `/tmp` itself.
This allowed coincidentally named files placed in that directory to impact the
outcome of the test. Additionally, this made the second part of the test fail
on systems on which `$TMPDIR != /tmp`, because the inspected directory was
different from the one in which the mock files were being written. This fully
fixes the issue only partially solved in db2bc9e667a1.

https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
