    rrdtool plugin: Minor performance improvement.
    
    Replace the value_list_to_string() function with a version which is optimized
    for data sets with a single data source. The original function is still used
    for data sets with multiple data sources. This allows to reduce the number of
    calls to snprintf() in this (very common) case, resulting in ~2% speedup.
