Replaced use of com.kstruct.gethostname4j.Hostname.getHostname() with env variable lookup HOSTNAME or COMPUTERNAME), with fallback to InetAddress.getLocalHost().getHostName().

Pull request overview

Replaces usage of com.kstruct.gethostname4j for agent hostname detection with environment-variable lookup (HOSTNAME / COMPUTERNAME) and a Java networking fallback, and removes the associated native/JNA dependencies from builds and assemblies.

Changes:

• Removed gethostname4j and JNA dependencies/version properties from Maven poms and distribution assembly descriptors.
• Updated RangerRESTUtils to resolve hostname via env vars with fallback to InetAddress.getLocalHost().getHostName().
• Updated the audit handler unit test to assert that agentHostname is non-blank rather than a hardcoded value.
