test/run: Exit on error from tests

Currently, result isn't saved outside of the scope of run_test, so we
always exit on error here.  An easier way to deal with having test/run
show failures is to exit on failure.

Automation is only as good as the humans behind it.  If you forget, like
I did, that you finally fixed Jenkins to email you every time, that lack
of emails about my non-travis jobs failing wasn't "no problems", it was
"You forgot to migrate all the Docker stuff to the new build server".
So, I'm going to apply this ASAP as I would not have let in the
u-boot-dm PR, had my setup been functioning as expected.
