mod_pubsub_serverinfo: Update to use mod_server_info (fixes #1841)
...but only for Prosody trunk users, because 0.12 mod_server_contact_info does
not use the new API in mod_server_info.

This module publishes data from [Prosody's `internal` statistics][doc:statistics]
into a PubSub node in [XEP-0039] format.
The node defaults to `stats` but can be changed with the option
`pubsub_stats_node`.
``` lua
Component "pubsub.example.com" "pubsub"
modules_enabled = {
"pubsub_stats";
}
pubsub_stats_node = "statistics"
```
