tests: move login tests from doctest to separate file

This way we can skip ENOENT (which happens in containers).
While at it, let's extend the tests a bit, so that we at least
call all functions and check the type of the return value.

Also, drop '.nspawn' from the machine name, nspawn doesn't
use that suffix any more.
