systemc: Hook up sc_main.

sc_main is exported as a python method on the SystemC_Kernel class and
takes a series of string arguments. The internal c++ implementation
converts those arguments into the standard argc and argv and uses them
to call the standard SystemC version of that function.

A weak SystemC version of sc_main is provided so that systemc will
compile with or without a simulation provided version of that
function. The weak version just complains and dies.
