Fix lib64 detection for 7 libraries and resolve double-slash paths
Fixes #3404: Configure script fails to detect lib64-installed libraries

This commit addresses the configure script's inability to detect YAJL, LMDB,
and PCRE2 libraries when installed in lib64 directories, and extends the fix
to all library detection scripts to ensure comprehensive lib64 support across
the entire ModSecurity build system.

Libraries fixed with lib64 detection support:
- build/yajl.m4 - YAJL JSON parsing library (lines 7096, 7164)
- build/lmdb.m4 - Lightning Memory-Mapped Database (lines 7870, 7945)
- build/pcre2.m4 - Perl Compatible Regular Expressions v2 (lines 9086, 9161)
- build/lua.m4 - Lua scripting language
- build/ssdeep.m4 - SSDEEP fuzzy hashing library
- build/libgeoip.m4 - GeoIP library
- build/libmaxmind.m4 - MaxMind library

Additional improvements:
- Fix double-slash path issues by removing trailing slashes from path assignments
- Follow existing pattern used by MaxMind and other libraries
- Total: 12 lib64 detection points added across all library detection scripts

Impact:
- Resolves compilation failures on systems using lib64 directories
- Enables ModSecurity compilation in container environments
- Supports standard 64-bit library installation paths
- Provides comprehensive lib64 support across all library dependencies

Tested on multiple Linux distributions:
- Alma Linux 9, 10
- CentOS Stream 9, 10
- Oracle Linux 9, 10
- Rocky Linux 9, 10
- Ubuntu 22.04, 24.04
- Debian 12, 13

Closes #3404
