Ignore pipefail alternative error when not a tty.

This happens with the basic-truncate test, only. It's the only user
of the `yes` program.

The `yes` command normally fails gracefully under the usual runs that
are attached to some terminal. But when the test script runs entirely
under something else, it will throw a needless error message that
pollutes the test output:

  `yes: standard output: Broken pipe`

Adjust the redirect to omit all stderr for `yes` in this case.
