AU/unittest: postinstall tests use uniquely named stateful + working directories
This should allow these tests to be run in parallel. Also includes an
extension to PostinstallRunnerAction and two global powerwash marker
utility functions to allow testing with uniquely named marker file paths
(necessary to avoid race conditions when multiple tests are run in
parallel).
BUG=chromium:236465
TEST=Uniquely named directories created, used and removed.
