Update zlib-src directory to use zlib 1.2.11
#123245: perl 5.26.1 is vulnerable to CVE-2016-9843, CVE-2016-9841, CVE-2016-9840, CVE-2016-9842Zlib.xs
Don't allow offset to be greater than length of buffer in crc32.Zlib.xs
Change my_zcalloc to use safecalloc.
The link, https://github.com/madler/zlib/issues/253, is the upstream report for the remaining
valgrind errors not already dealt with by 1.2.11. Using calloc in Zlib.xs for now as a workaround.
