    Low: ping: Log sensible error when /tmp is full (bsc#987348)
    
    In fping_check, two temporary files are created in /tmp.
    If /tmp is full, the creation fails silently and subsequently
    the ping registers no connection to the targets.
    
    With this change, the problem is caught and reported.
