run-tests: handle --jobs and --first gracefully

Without this change, --first causes currently-running tests to explode
in violent and surprising ways when their temporary directory gets
cleaned up. Now we just suppress failure messages from non-first
failures when running in --first mode.

try:
    import coverage
    getattr(coverage, 'process_startup', lambda: None)()
except ImportError:
    pass
