selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT
The PREEMPT_RT patchset does not use do_softirq() function thus trying
to filter for do_softirq fails for such kernel:
echo do_softirq
ftracetest: 81: echo: echo: I/O error
Choose some other visible function for the test. The function does not
have to be actually executed during the test, because it is only testing
filter API interface.
