0001-Fix-cache-file-update-on-MinGW-and-Cygwin.patch

If you have an old cache file and need updating, the updating fails on Windows
(both MinGW and Cygwin).

On Windows, opened or locked files cannot be removed.
Since fontconfig locked an old cache file while updating the file, fontconfig
failed to replace the file with updated file on Windows.

I've created a patch.
It makes fontconfig does not lock the old cache file while updating it on
Windows (both MinGW and Cygwin).
