[BTRACE-47] OnTimer annotation prevents traced application from exiting

The @ontimer annotation creates a non-daemon Timer object that continues to run even after the traced application exits. When experimenting with the provided ThreadCounter btrace script, the Timer thread continues to run. When the @ontimer annotation is commented out, the traced application halts.

{{java -javaagent:$

{BTRACE_HOME}

/build/btrace-agent.jar=stdout=true,noServer=true,script=ThreadCounter.class ThreadTest}}

By configuring the Timer object to use daemon threads, the traced application correctly exits.
