Subject: [PATCH] timeout: ensure --foreground -k exits with status 137

* src/timeout.c (main): Propagate the killed status from the child.
* doc/coreutils.texi (timeout invocation): Remove the
description of the --foreground specific handling of SIGKILL,
now that it's consistent with the default mode of operation.
* tests/misc/timeout.sh: Add a test case.
* NEWS: Mention the change in behavior.
Fixes https://bugs.gnu.org/51135
