trace2: avoid emitting 'def_param' set more than once

During nested alias expansion it is possible for
"trace2_cmd_list_config()" and "trace2_cmd_list_env_vars()"
to be called more than once.  This causes a full set of
'def_param' events to be emitted each time.  Let's avoid
that.

Add code to those two functions to only emit them once.
