Problems with up-to-date hawtjni

[thedeadliestcatch]

I'm attaching my current fixes based off PR 31 and 32, and another user's modification to support a YARA_HOME environment variable to allow using explicit paths for the libyara dependency.

Unfortunately, there is one extant issue I have not yet solved:

This is the versioning of the JDK/env from the image I am using to build:

$ java -version
openjdk version "21.0.4" 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode, sharing)

Should be reproducible as-is.

Hopefully this gets things moving toward a usable state.
