Subject: [PATCH] Fix ModSecurity LMDB dependency crash (Issue #1626)

- Always download compatible ModSecurity binary after installation
- Removes conditional check for custom_ols_marker
- Fixes undefined symbol: mdb_env_create error
- Prevents OpenLiteSpeed crashes with SIGSEGV signal 11
- Compatible with Ubuntu 24.04, RHEL 8/9, Debian 11/12

The fix ensures that compatible ModSecurity binaries (built without
LMDB dependency or with LMDB statically linked) are always used,
preventing the runtime symbol lookup errors that cause crashes.
