package/modsecurity2: security bump to version 2.9.7

- Fix CVE-2023-24021: Incorrect handling of '\0' bytes in file uploads
  in ModSecurity before 2.9.7 may allow for Web Application Firewall
  bypasses and buffer overflows on the Web Application Firewall when
  executing rules that read the FILES_TMP_CONTENT collection.
- host-pkgconf is mandatory and used to find libxml2 since
  https://github.com/SpiderLabs/ModSecurity/commit/baa38ddbaf55a87afecad7a1e1760c69a2689787
- pcre2 is supported since:
  https://github.com/SpiderLabs/ModSecurity/commit/8fc0b519b7a6c023259753a21f33bf3649a25b14
