pactest: remove need for pause when running tests

Instead of pausing 1.5 seconds on tests that check file mtimes, change the
mtimes to something in the far past so we can immediately tell if a file was
modified and/or touched. This saves a decent amount of time on the upgrade
tests which often check mtimes.

355 was a completely arbitrary time value, don't ask me why I picked it.
