websites: chmod777.sh: Switch to mod_md for cert

The _chmod777.sh_ site now obtains its certificate from Let's
Encrypt using the Apache _mod_md_ (managed domain) module.  This
dramatically simplifies the deployment of this certificate, eliminating
the need for _cert-manager_ to obtain it, _cert-exporter_ to add it to
_certs.git_, and Jenkins to push it out to the web server.
