Fix up symlinks in exif bump

Previous exif bump copied the newer version into
mediagoblin/tools/extlib/exif but not in extlib/exif. Fix this by
bumping extlib/exif and symlinking to tools/extlib/exif.

Do note that this is still the version fetched from http://sourceforge.net/projects/exif-py/
while the upstream maintainer seems to be active on:
https://github.com/ianare/exif-py

(The sf.net download is quite new though)
