This patch extends the integration tests for `tailscale up` to include tailnets
where new devices need to be approved. It doesn't change the CLI, because it's
mostly working correctly already -- these tests are just to prevent future
regressions.
I've added support for `MachineAuthorized` to mock control, and I've refactored
`TestOneNodeUpAuth` to be more flexible. It now takes a sequence of steps to
run and asserts whether we got a login URL and/or machine approval URL after
each step.
