Apache php8 module looking for argon2 library in /usr/lib due to wrong rpath

[jrcii (John Cornell)]

Expected: start apache successfully with mod_php80 in httpd.conf

Observed: apache says that mod_php80 is trying to load @rpath/libargon2.1.dylib and can't find the image

Steps to reproduce: install apache2, php80, and php80-apache2handler, and try /opt/local/sbin/httpd -k start

Temporary Fix: sudo install_name_tool -add_rpath /opt/local/lib /opt/local/lib/apache2/modules/mod_php80.so

I'm reciting these errors, paths, and filenames from memory so sorry if they're a bit off.
