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
properly. This is an interim hack.

Brad Fitzpatrick ba1adf6c24 ssh/tailssh: make pty termios options match OpenSSH
Still not sure the exact rules of how/when/who's supposed to set
these, but this works for now on making them match. Baby steps.
Will research more and adjust later.
