[issue22821] Argument of wrong type is passed to fcntl()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Arguments of wrong type is passed to C function fcntl() in the fcntl module.

Third argument of fcntl() should be either pointer to binary structure or C int. But C long is passed instead. All works on platforms where sizeof(long) == sizeof(int) or on little-endian platforms, but on big-endian platform with sizeof(long) != sizeof(int) this will pass wrong value.
