    Fix overflow in thumbnail cache housekeeping
    
    g_settings_get_int gives a signed 32 bit integer, so setting the thumbnail cache size to 5120 MB (for 
example) resulted in an overflow to 1 GB.
    
    Tested on my computer by changing the cache size to a value that would previously overflow and observing 
the size of ~/.cache/thumbnails.
