Summary

Report the delivery of signals to processes other than self while
Capsicum violation tracing with CAPFAIL_SIGNAL.

Programs that are not yet Capsicumized may be traced to discover
potential capability failures. With `ktrace -t p` and kdump, you
are given a list of syscalls as a starting point for program
Capsicumization.
