[dev.fuzz] internal/fuzz: improve handling of worker termination by signal

With this change, we'll no longer silently ignore terminations by
SIGKILL. We use SIGKILL to terminate unresponsive workers, but it can
also be delivered by the OOM killer.

When a worker is terminated by a signal not apparently due to a crash
or interruption (like SIGKILL or SIGHUP, as opposed to SIGSEGV), we'll
log a message, but we won't record a crash, since any given input is
not likely to reproduce this termination.

Fixes golang/go#46576
