Subject: [PATCH 1/2] virt: Simplify UserIterface::set_inner signature

In practice, the impl Into only makes things more complicated because
type inference does not work and users need to add type annotations:

So we can also just pass the box directly.

Subject: [PATCH 2/2] virt: Make default user presence level configurable

This makes it easier to test different user presence levels without
having to implement the full UserInterface trait.
