Developer 5e31a1584a Fix: Apply MEDIUM priority improvements to malware scanner ecosystem
MEDIUM PRIORITY FIXES:
- [M1] RKHunter: Dynamic config file detection with fallback
- [M2] Imunify: Support both ImunifyAV and Imunify360 variants
- [M3] ModSecurity: OS-aware audit log path detection (Debian vs RHEL)
- [M5] Maldet: Fallback directory system for update logs (not hardcoded /tmp)

IMPROVEMENTS:
- Robustness: More resilient to different installation paths and configurations
- Cross-platform: Better handling of OS-specific paths and tools
- Reliability: Respects filesystem permissions when writing logs

Tested:
- Both files pass bash -n syntax validation
- Multi-platform compatibility verified
- All previous CRITICAL and HIGH fixes intact
