src: Remove lttng support.

This cleans up and removes lttng support completely. Recent discussion
on a PR to deprecate lttng suggested that we remove it completely
pending feedback from the TSC.

This should be considered a non breaking change, as a recent PR reveals
that compiling with this system has been broken for nearly two years.
