haproxy: update to v3.2.4

haproxy: update to v3.2.4

- Major version bump to the latest HAProxy v3.2 LTS release.
- Updated haproxy PKG_VERSION and PKG_HASH
- Updated build-parameters:
  - Removed USE_QUIC_OPENSSL_COMPAT as OpenSSL v3.5.1+ ships with
    good enough Quic support. HAProxy does not need the compat code
    with these newer versions of OpenSSL anymore.
  - Removed obsolete build parameters.
- Updated example configuration so it works with the new version.
- See changes: http://git.haproxy.org/?p=haproxy-3.2.git;a=shortlog
