testutil: Silence an empty body warning on TimeBombAbort.

When the TimeBombAbort time is exceeded, the signal handler prints
a message on stderr and exits. If printing the error message fails,
there's nothing else the program can do, so we simply ignore that
case. This patch silences this warning.
