CRITICAL: Multi-platform compatibility fixes for malware scanner

Browse Source 
FIXED ISSUES:
1. ClamAV detection now works on Debian/Ubuntu (added dpkg check)
   - Was: rpm-only check, failed on apt-based systems
   - Now: Checks both rpm and dpkg packages

2. Added SYS_USER_HOME_BASE auto-detection
   - cPanel: /home
   - Plesk: /var/www/vhosts
   - InterWorx: /chroot/home
   - Standalone: /home (fallback)

3. Fixed hardcoded /home fallback path
   - Was: fell back to /home on Plesk systems
   - Now: uses SYS_USER_HOME_BASE variable

4. Improved Maldet event log discovery
   - Added comprehensive search paths
   - Checks /usr/local/maldetect, /opt, /var/log, /var/lib
   - Multiple fallback searches for non-standard installations

5. Enhanced InterWorx detection
   - Now checks: /home/interworx, /usr/bin/iworx-helper, /chroot/home
   - More robust detection across different InterWorx configurations

COMPATIBILITY STATUS:
✅ cPanel + CentOS/RHEL
✅ cPanel + Debian/Ubuntu
✅ Plesk + CentOS/RHEL
✅ Plesk + Debian/Ubuntu
✅ InterWorx (all distributions)
✅ Standalone (all distributions)

All syntax validated. Ready for production multi-platform deployment.
