Include "mozzconf.h".

This change includes "mozzconf.h" in our copy of 'zconf.h' as we did before updating to zlib 1.2.5 to avoid symbol conflicts with sdch happening when we use supalink.

BUG=none
TEST=link Chromium with supalink.

@@ -11,3 +11,4 @@ A few minor changes, all marked with "Google":
 - Added #ifdefs to avoid compile warnings when NO_GZCOMPRESS is defined.
 - Removed use of strerror for WinCE in gzio.c.
 - Added 'int z_errno' global for WinCE, to which 'errno' is defined in zutil.h.
+- Added 'mozzconf.h' to mangle the function names.
