Add back unit test for usb_pd"
This is mostly the same as previous commits, but with increased delay.
Previously, we have short delays (e.g. 3ms) which is too short and may
cause instability.
Now that we have slowed down the time when running unit tests and
increased the delay, this shouldn't cause problems anymore.
BUG=chrome-os-partner:31200
TEST=Repeatedly run multiple unit tests in parallel.
BRANCH=Samus
