fix zlibWrapper for Visual Studio

Browse Source 
As per https://github.com/facebook/zstd/issues/1800#issuecomment-545945050,
Visual does not support `ssize_t` type,
which is an issue for `gzread.c`.

Added a work around, suggested by @bluenlive

Note : I have not been able to confirm the problem,
so this is a blind fix.
This seems safe outside of Visual, since it is gated by _MSC_VER macro.
