tracing: Make tracing_selftest_running global to the tracing subsystem 

The file trace.c has become a catchall for most things tracing. Start
making it smaller by breaking out various aspects into their own files.

Make the variable tracing_selftest_running global so that it can be used
by other files in the tracing subsystem and trace.c can be split up.
