scons: Rework the fastmodel extract_var helper.
This helper extracts config variables and sets them up for use in
fast model tools. Rework this function for two purposes. First, ensure
that the ['CONF'] subdict is used consistently. It was used in one spot
in that function, but not anywhere else. Avoid those mistakes by
accessing the configuration dict only once, and then reusing the value.
Second, only print the values of those variables if they aren't empty.
That avoids extra log output for values which aren't set up and aren't
being used, while still exposing those values if they are set up. This
will print them even if they aren't being actively used, but are set up
and could be with other changes in the config.
