Get the own domid via creation of a temporary event channel. There is
no "official" way to read the own domid in PV guests, so use the event

- read the event channel status which will contain the own domid in
unbound.dom
- close the event channel

I think the function name should be generic so the caller doesn't need
to be modified everytime the implementation is updated.
How about get_domid()?
