Apache httpd by default blocks URL-encoded / (%2F) characters in the
URL path, even though these are RFC-compliant. Enable them and permit
their safe passage to the debuginfod servers.

Our ansible default ansible scripts don't like multiple /suburls being
individually proxied, so we ended up losing /buildid/* and keeping
/metrics.
Switch to using single /-level reverse-proxying AND wiki-redirection
clauses, and use a new template .conf file to break the tie with a
"ProxyPass / !" directive.
