updated minizip to last version (#5498)

Version 1.3.1 has these key changes:

Reject overflows of zip header fields in minizip
Fix bug in inflateSync() for data held in bit buffer
Add LIT_MEM define to use more memory for a small deflate speedup
Fix decision on the emission of Zip64 end records in minizip
Add bounds checking to ERR_MSG() macro, used by zError()
Neutralize zip file traversal attacks in miniunz
Fix a bug in ZLIB_DEBUG compiles in check_match()
Version 1.3 has these key changes:

Building using K&R (pre-ANSI) function definitions is no longer supported.
Fixed a bug in deflateBound() for level 0 and memLevel 9.
Fixed a bug when gzungetc() is used immediately after gzopen().
Fixed a bug when using gzflush() with a very small buffer.
Fixed a crash when gzsetparams() is attempted for a transparent write.
Fixed test/example.c to work with FORCE_STORED.
Fixed minizip to allow it to open an empty zip file.
Fixed reading disk number start on zip64 files in minizip.
Fixed a logic error in minizip argument processing.
