signals: don't call a print routine in a signal handler
Print routines are not asynchronous-safe. But... the only reason the call of kill() could return an error code is when the relevant process has already terminated -- which is not a problem, because that was the goal of calling kill(). This fixes https://savannah.gnu.org/bugs/?54409. Reported-by: Daniel Kozovsky <dkozovsk@redhat.com>master
