Subject: timeout: handle signals more transparently

* m4/jm-macros.m4: Define HAVE_SETRLIMIT.
* src/timeout.c: If the child exited with a signal,
raise that signal to the timeout process itself,
so that callers may also see the signal status.
Use setrlimit to disable core dumps for the timeout
process, which would be generated by some signals.
