[m-rev.] diff: disable a test case in C# and Java grades

[Julien Fischer]

Disable a test case in C# and Java grades.

tests/parj_conj/Mmakefile:
    Disable the pathological_right_recursion test in C# and Java grades.
    For those target languages, this test will exceed the default stack limits
    in the respective runtimes. While it is possible for the test to succeed
    by increasing those limits, it's not worth the trouble here as this is a
    test for parallel conjunction and that is not currently supported when the
    target language is C# or Java.

Julien.
