msys-gzip: Add missing binary mode patch from upstream which makes it usable again

1.6-1 is not able to compress and decompress data.
Perfectly seen also in the git test t5000 45/46.

And I guess this is also the reason why the jenkins jobs do not work anymore.
Sorry for the mess.

Packages are available [here](http://virtuell-zuhause.de/public-downloads/msys-gzip-1.6-2/)
Please add one more space here to align the "u"s :-)
