selftests/ftrace: event_triggers: wait longer for test_event_enable

Browse source 
[ Upstream commit a1d6cd88c8 ]

In some platform, the schedule event may came slowly, delay 100ms can't
cover it.

I was notice that on my board which running in low cpu_freq,and this
selftests allways gose fail.

So maybe we can check more times here to wait longer.
