script: Minor cleanups.

- Instead of using isatty() to decide whether to call tcgetattr(), just
  call tcgetattr() directly, since that's all that isatty() does anyway.
- Simplify error handling in termset().  Check for errno != ENOTTY from
  tcgetattr() to handle errors that may be raised while running
  script(1) under a debugger.
