Recompile tod drivers using libfprint-tod-test-drivers project [1] so
that we don't have to reorder the private driver structure, plus use a
versioned driver ID and parse it to check whether a feature is supported
for such TOD test driver.

This will allow libfprint to cancel operations internally in the future.
If the internal cancellation method is used, then the private
current_cancellation_reason variable must be set to the GError. This
error will be returned when set.
