security/tripwire: Update 2.4.3.7 --> 2.4.3.8

Tripwire pull request #39,

• Clean up some issues building with -std=c++17
• Regenerate buildsys files with automake 1.16
• Improve non-gcc compiler detection
• Use standard fixed-width int types instead of rolling our own, if they're available.
• Bump up the copyright year again.

This fixes many build failures due to the LLVM16 import.
