Cleanup: remove useless lttng_ust_probe_supports_event_notifier

LTTng-UST 2.13 bumps the accepted probe provider major version to 3,
therefore we can remove the lttng_ust_probe_supports_event_notifier
version check, which requires that the probe provider major version is
>= 2, because it is now useless.
