[PATCH] tests: Avoid skipping stty-* tests.

[Nix]

tests/test-lib.sh (require_controlling_input_terminal_): Check stdout,
not stdin.
---
This testsuite bug causes the stty tests to be skipped, always, because
it's testing stdout, not stdin, and the testsuite engine redirects stdout
to a logfile. They still pass, despite not being run for lo these many
years.

Patch against HEAD. (I'm pretty certain it doesn't require a copyright
assignment. ;) )
