upstream fix for deflate.c

I've just upgraded my FreeBSD 11.0 server upto recent 11.1-STABLE without
touching other software. The server runs UniFi Controller containing embedded
Tomcat web server that uses gzip to compress HTML responses.

After FreeBSD upgrade, it started producing broken gzip stream and "curl -vvvv
--compress localhost:8880/guest/s/default/" confirms that complaining "Error
while processing content unencoding: invalid block type".

The problem is exactly the same described in
https://bugs.launchpad.net/ubuntu/+source/zlib/+bug/1692870 that points to the
upstream fix:
https://github.com/madler/zlib/commit/f9694097dd69354b03cb8af959094c7f260db0a1#diff-766e4159febe3390b2e58127d6c973d3
that I've attached to this PR (deflate.c part, without comment part in zlib.h)

This patch fixes the problem.
