systemc: config: Don't inject a custom argv[0] in sc_main.py.

argv[0] is already part of sys.argv, so we don't need to add an
additional argument in front of sys.argv.

The argv[0] which is used in gem5 config scripts is the name of the
config script itself. While it might seem a little odd for the name of
a systemc program to end in .py, it's as arbitrary as any other name,
and generally shouldn't cause a problem. If some other more
sophisticated mechanism for setting argv[0] is necessary, then the user
can write a very slightly more complicated version of this script with
additional logic.
