The test harness provides a TMP directory for tests to use. It's badly
named. It's meant to be more of a scratch directory that is not on the
FS being tested.
Tests use it both for small log files that give insight into the
platform and for large generated files that are not worth saving. We
want to save the directory after test runs to get at the log files, but
we don't want to burn a ton of space also saving large generated files
This updates the handful of tests to remove their handful of files that
are large enough to be a problem. With these out of the way we can save
the tmp/ directory without its space consumption getting out of hand.
