Subject: [PATCH] test: stop changing argv[0] for forked tests

This was useful when we had a small number of test-forks with the suites
distributed. It helped debug which one is still running and then which suites
are in it. Now that we simply distributed everything across the forks it
doesn't have a lot of usefulness and it interferes with the ability to
backtrace properly.
