Make OpenSSH work with utmpx.

- Partially revert r184122 (sshd.c). Our ut_host is now big enough to
  fit proper hostnames.

- Change config.h to match reality.

- defines.h requires UTMPX_FILE to be set by <utmpx.h> before it allows
  the utmpx code to work. This makes no sense to me. I've already
  mentioned this upstream.

- Add our own platform-specific handling of lastlog. The version I will
  send to the OpenSSH folks will use proper autoconf generated
  definitions instead of `#if 1'.
