contrib: Update to zlib 1.2.11.

Add patch to fix cross-compiling (win32/Makefile.gcc doesn't work).

See:
https://github.com/madler/zlib/commit/a72bcd5607a6b7f48a78c1485783c55389d18f55
https://github.com/madler/zlib/commit/148b8f630ced4e84264201fc94f07568dff6b3a2

...for what not to do. There's more of course. *sigh*
