third_party: Remove zlib from third_party

We require zlib 1.2.3.

We stopped requring a patched zlib with 5631a1b9bc03d6cf31af66b13872255f18979fe8

As discussed on samba-technical here:

https://lists.samba.org/archive/samba-technical/2019-May/133476.html

In short, zlib contains some (old, now broken) crypto code that while not compiled
in Samba is best left out of our tarball to ease crypto audits.  It is also very
very out of date and is a slightly modified copy of something otherwise very
likely available on our supported host OSs.  It would be strange to say that
GnuTLS and dependencies are an acceptable burden to install but say zlib is
a step to far.

So it is removed from Samba's third_party with this commit.

The diff between zlib in Samba and official zlib 1.2.3 is included
in third_party/zlib/last-samba-from-1.2.3.diff

-Possible upgrades to gzfilebuf:
-
-- The ability to do putback (e.g. putbackfail)
-
-- The ability to seek (zlib supports this, but could be slow/tricky)
-
-- Simultaneous read/write access (does it make sense?)
-
-- Support for ios_base::ate open mode
-
-- Locale support?
-
-- Check public interface to see which calls give problems
-  (due to dependence on library internals)
-
-- Override operator<<(ostream&, gzfilebuf*) to allow direct copying
-  of stream buffer to stream ( i.e. os << is.rdbuf(); )
