Refactor: GAtPPP connect callback

The connect callback was not giving enough information and the
information it was providing was not in a convenient form.

- Provide the ppp interface name (e.g. tun0)
- Provide ip, dns1 & dns2 as strings
- Do not send the ppp structure in the callback, it is most likely
  present in the user data anyway
