This fixes crash for people who have live ejabberd installed in make install
target directory, by ensuring that loaded binaries aren't replaced in memory
with new content.

The option allows to set arbitrary text for disco#info identity name.
Previously, option 'name' was supported by mod_proxy65 and mod_http_upload
only. Now, all the following modules support this option as well:
- mod_disco
- mod_irc
- mod_muc
- mod_multicast
- mod_pubsub
- mod_vcard

Example:
```
modules:
  ...
  mod_disco:
    name: "Cool XMPP Server"
  ...
```

Copyright dates in vCards may paritally disclose server version,
which is not always desired
