systemc: configs: Add a very simple config which just runs sc_main.
This config will just run the sc_main function (which must have been
provided in c++ somehow), passing through any of the scripts command
line arguments to sc_main.
Needing to do this sort of thing is common enough that there should be
a canned config which supports it.
