test-cmd/tty.sh: Skip on system tty exiting with >1

For example in this particular case:
  $ tty
  tty: ttyname: No such file or directory
  [2] $

Which can't reasonably be handled due to error codes and the
formatting of failures being non-standard,
in fact $?=1 only got standardized in POSIX.1-2024.
