fix xpcshell harness to run single threaded for each test, even if we are running many tests in parallel
in working on taskcluster we found that when enabling >1 core for ec2 instances our xpcshell tests became much more intermittent: https://bugzilla.mozilla.org/show_bug.cgi?id=1237024#c1 This is because we use: from multiprocessing import cpu_count We should use a different method for determining the accurate amount of cores available. More info on the slight misreporting here: http://stackoverflow.com/questions/31346974/portable-way-of-detecting-number-of-usable-cpus-in-python
