selftests/ftrace: Do not to use absolute debugfs path

Browse Source 
[ Upstream commit ba1b9c5048e43716921abe3a1db19cebebf4a5f5 ]

Use relative path to trigger file instead of absolute debugfs path,
because if the user uses tracefs instead of debugfs, it can be
mounted at /sys/kernel/tracing.
Anyway, since the ftracetest is designed to be run at the tracing
directory, user doesn't need to use absolute path.
