tracing: Remove dummy options and flags

Browse source

When a tracer does not define their own flags, dummy options and flags are
used so that the values are always valid. There's not that many locations
that reference these values so having dummy versions just complicates the
code. Remove the dummy values and just check for NULL when appropriate.
