patch for mod_extdisco.lua

[Alexey Bobyr]

Hi,

According to https://xmpp.org/extensions/attic/xep-0215-0.6.html service tag must is a child element of 'services' tag in reply.

Attached patch adds main tag services.

Please note that https://xmpp.org/extensions/xep-0215.html now contains urn:xmpp:extdisco:2

So maybe need to change mod_extdisco description that it adds support of XEP-0215 its not true anymore. 

Current version of mod_extdisco gives support for first version of XEP-0215.

Thanks. Patch looks good. I noticed that the other handler has the same issue.

Looks like the incompatible changes between the :1 and :2 namespace
mainly concern service pushes, which is not implemented here.
