    oeqa/core/runner: OEStreamLogger don't buffer test execution writes
    
    Since OEQA framework uses Python logging functionality to report test
    results there is a class that wraps PyUnit writes into logging commands
    (OEStreamLogger), so don't buffer the actual test execution to have
    insight of what is currently executing.
    
    This fix will change a little the test output format adding an '\n'
    previous the test result, for example:
    
    From:
    
    test_nonmatching_checksum (lic_checksum.LicenseTests) ... ok
    
    To:
    
    test_nonmatching_checksum (lic_checksum.LicenseTests)
     ... ok
    
    This is because the new line added by the PyUnit StreamLogger because
    currently we don't have a manner to identify when a test execution
    starts at report level (write msg).
