Fix potential vulnerable cloned functions

[npt-1707]

Hi there,

I identified other potential vulnerabilities in clone functions in libraries/tiff/tools sourced from vadz/libtiff. This issue, originally reported in CVE-2016-9534, was resolved in the repository via this commit https://github.com/vadz/libtiff/commit/83a4b92815ea04969d494416eaae3d4c6b338e4a.

This PR applies the corresponding patch to fix the vulnerabilities in this codebase.

Additionally, I suggest updating the latest version of this library to avoid unexpected vulnerability.

Please review at your convenience. Thank you!
