SpecialUploadStash: Disable output gzipping when outputting remove scaled thumb

This is the only code path that wasn't calling wfResetOutputBuffers()
already. All other ones end up in outputLocalFile(), which calls
it via StreamFile::prepareForStream().

I can't really tell why this causes Varnish stuff to go bust, but it's
definitely the right thing to do anyway.
