[SECURITY] Fix unsafe subprocess invocation in Phunter integration (intelowlproject#3464)

* Refactor: Pass subprocess command arguments as a list directly to improve execution.

* chore: Add license header and remove unused `shlex` import.

* fix(phunter): use absolute path for python executable to satisfy security linter
