Brad Fitzpatrick 012098ec32 ssh/tailssh: fix terminal corruption (temporary hack)
Maisem figured out the real problem but will take several commits
(e.g. tailscale/ssh#2) in different repos to get it fixed

Details of real fix:

Brad Fitzpatrick c9eca9451a ssh: make it build on darwin
For local dev testing initially. Product-wise, it'll probably only be
workable on the two unsandboxed builds.

Brad Fitzpatrick 1b5bb2e81d ssh/tailssh: rename sshContext to sshConnInfo
So it's not confused for a context.Context and we can add contexts
later and not look like we have two.

Brad Fitzpatrick fbff1555fc ipnlocal, tailssh: start moving host key stuff into the right spot
Make tailssh ask LocalBackend for the SSH hostkeys, as we'll need to
distribute them to peers.

For now only the hacky use-same-as-actual-host mode is implemented.
