Resolve Swift warnings by specifying void arguments
Resolve Swift warnings by specifying void arguments

The following functions in the `fork.h` file cause a `This function declaration is not a prototype` warning in Swift:
```
void grpc_prefork(void);

void grpc_postfork_parent(void);

void grpc_postfork_child(void);

void grpc_fork_handlers_auto_register(void);
```

Explicitly specifying `void` as the argument resolves the warnings.

Reproducible using Xcode 9.2 with `SwiftGRPC`/`gRPC-Core` via CocoaPods.
