tracing: excise the tcg related from tracetool

Now we have no TCG trace events and no longer handle them in the code
we can remove the handling from the tracetool to generate them. vcpu
tracing is still available although the existing syscall event is an
exercise in redundancy (plugins and -strace can also get the
information).
