If you specify a URL ending in /, BitBake's fetcher returns a localpath
of ${DL_DIR}, and if you then try to unpack that it will attempt to copy
the entire DL_DIR contents to the destination - which at least on my
system filled my entire /tmp. Obviously we should fix the fetcher, but
at least detect and stop that from happening here for now.
