When inferring whether to use TTY, check both stdin and stdout are
terminals.

Otherwise, we get failures like the following:

$ nomad alloc exec --job example echo hi
hi
$ echo | nomad alloc exec --job example echo hi
hi
$ nomad alloc exec --job example echo hi | head -n1
failed to exec into task: not a terminal
