This data was planned in the initial LTTV versions, but did depend on
grabbing system information from a /proc text file. I removed this so
that we do not even depend on /proc being active or mounted on the
system, so all the information can be extracted through LTTng channels.
So if we implement something like ltt_trace_system_description, we would
have to export more information from the kernel through the standard
LTTng tracing infrastructure.
