[issue3194] Demo/loop.c passing "char *" instead of "wchar_t *"

[Rafael Zanella]

New submission from Rafael Zanella <rafael.zanella at yahoo.com.br>:

The Demo/loop.c passes a char pointer (argv[0]) while 
Py_SetProgramName() now expects a wchar_t pointer.

I've attached a patch, the solution on the patch was borrowed,
ok stolen, from Python/frozenmain.c
