Fix the automated regression check
It seems that this was a thing before, but I guess it had bit-rotted.
This updates it to use the new `--presubmit` option to the touch tests,
which only fails if a regression occurs in a known test or an unknown
(new) test fails.
BUG=None
TEST=cause a regression and check the presubmit fails
