rS321465: Add a simple script which calls open(2) and others to generate events for
Summary

This test timeout on a quiet system because there is nobody triggers
syscall::open:entry and syscall::: probe while test execution.

Add a simple script to generate some noise, it sleeps for 1 second at begining
because current dtest script doesn't support execute a program after invoking
dtrace script.

Test Plan

cd /usr/tests/cddl/usr.sbin/dtrace/common/speculation && kyua debug t_dtrace_contrib:tst_NoSpecBuffer_d

That's not a binary file, it's a script which needs to be run while test running, like other .exe files in test suite. arc(1) treats it as binary...

This is susceptible to the same race I mentioned in the other review. IMO it is better to just loop forever and let the test harness kill the .exe process once the test has passed.
