    test_smb: skip test_smb_service_s4u2self for fed31
    
    The test test_integration/test_smb.py::TestSMB::test_smb_service_s4u2self
    is expected to fail in Fedora <= 31 as it requires krb >= 1.18
    that is shipped from fedora 32 only.
    
    Skip the test depending on the fedora version.
