[tracing] Depend on libtrace when that is what's really meant

libtrace-provider has libtrace listed as a dependency when really it
does not have any such dependency. This lets trace clients use
libtrace-provider as a dependency when what they really mean is libtrace.

This errant dependency in trace-provider is being fixed, which
means we need to fix these clients.
