timeout: with --foreground don't send SIGCONT
* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program
when --foreground is specified, as it's generally not needed for
foreground programs, and can cause intermittent signal delivery
issues with monitors like GDB for example.
* doc/coreutils.texi (timeout invocation): Mention that SIGCONT
is not sent with --foreground.
* NEWS: Mention the behavior change.
