[PATCH 3/5] tracing: Make tracing_selftest_running/delete nops when not used

[Steven Rostedt]

From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

There's no reason to test the condition variables tracing_selftest_running
or tracing_selftest_delete when tracing selftests are not enabled. Make
them define 0s when not the selftests are not configured in.
