libtracefs: Add custom tracer to tracefs_tracer_set()
Allow the user to enter their own string to define a tracer using
TRACEFS_TRACER_CUSTOM. This way if there's a tracer that is not yet
supported by libtracefs, the user could still enable the tracer with the
tracefs_tracer_set() functionality, as well as use the enums to set
tracers.
For example:
tracefs_tracer_set(NULL, TRACEFS_TRACER_CUSTOM, "osnoise");
