test infra: enable single-worker rerun phase for flakey tests.

Use of --rerun-all-issues will enable any test method failure, not just
test methods marked with the flakey decorator, to rerun.

Currently this does not change the flakey logic's immediate rerun
attempt.  I want to make sure this doesn't cause any significant issues
before changing that part.

The rerun reporting is only known to work properly with the
default (new) BasicResultsFormatter reporting.  Once we work out
any issues, I'll go back and make sure the curses output handles
it properly as well.
