Update OS detection and binary distribution to support separate binaries
for AlmaLinux/RHEL 8 and 9. The new structure uses:
- rhel8/ directory for AlmaLinux/RHEL 8.x binaries
- rhel9/ directory for AlmaLinux/RHEL 9.x binaries
- ubuntu/ directory for Ubuntu/Debian binaries
Changes:
- Enhanced detectBinarySuffix() to distinguish between RHEL 8 and 9
- Updated binary URLs to use new directory structure
- Updated ModSecurity checksums for all OS variants
- Applied changes to install, upgrade, and ModSecurity modules
This ensures proper ABI compatibility by providing OS-specific builds
with correct glibc and library dependencies for each platform.
