The redirect URI specified in the Apache config for OIDC
was unintentionally serving a dual purpose as a redirect
URI and a handler for command line auth.
As of mod_auth_openidc v2.4.9 this no longer works.
This change splits the paths for command line auth and
the redirect URI into two to work around this.
