selftests/ftrace: Change synthetic event name for inter-event-combined test

Browse Source 
[ Upstream commit 96378b2088 ]

This test uses waking+wakeup_latency as an event name, which doesn't
make sense since it includes an operator.  Illegal names are now
detected by the synthetic event command parsing, which causes this
test to fail.  Change the name to 'waking_plus_wakeup_latency' to
prevent this.
