mingw-fetch-dependencies.sh: Don't pass -c to wget

Browse Source 
The -c option for wget and -C - option to curl are used to make it
continue the download if the file already exists. The idea was that it
wouldn't waste time downloading the files again if the file already
exists. However this causes problems if the remote file gets larger
because the download will continue from the size of the old file so it
will get corrupt. Instead let's just explicitly check if the file
already exists and avoid calling wget or curl altogether.
