Closes: #2244.
This patch disabled xmlrpc.php functionality entirely. For interacting with
WordPress using app, the new REST API functionality is recommended. However, for
the Pingback API XML-RPC is still a necessity. If this is an important feature
for FreedomBox users, we intend to re-enable XML-RPC functionality in WordPress.
