    run_tests.sh OS X script fixes

    On OS X, '*' is not a valid grep modified for '[^[:space:]:]', nor is it
    necessary when the lines being checked against must be prefixed with
    neutron.tests.
    Also, dirname was being called with an empty var, without quoting, resulting
    in usage errors.
