    libphobos: Run unittest tests with dg-runtest.
    
    Use `dg-runtest' test driver rather than `dg-test' to run the libphobos
    unittest testsuite, same as all other libphobos tests.  This prevents
    the tests from being ran multiple times when parallelized.
    
    Set `libphobos_test_name' as well so that all tests get a unique name.
    
    libphobos/ChangeLog:
    
            * testsuite/libphobos.unittest/unittest.exp: Use `dg-runtest' rather
            than `dg-test'.  Set `libphobos_test_name'.
