In addition to migrating the tracepoint overhead test from sample/bpf to selftest/bpf, this commit extends benchmarking test with rename task.
Since previous commit migrated tracepoint based on rename task, this commit updates the benchmarking program to utilize the newly added 'rename-tp'. Signed-off-by: Daniel T.
