    Cygwin: testsuite: Just log result of second open of /dev/dsp
    
    Do not rate successful second open of /dev/dsp as an error, just log the
    result.
    
    Based on this patch by Gerd Spalink:
    
    https://cygwin.com/pipermail/cygwin-patches/2004q3/004848.html
    
    Also, disable forkplaytest() which is broken in some complex way I don't
    understand.
