fuzz: Remove confusing return keyword from CallOneOf

The return type is already enforced to be void by the
ternary operator:

./test/fuzz/util.h:47:25: error: right operand to ? is void, but left operand is of type *OTHER_TYPE*
    ((i++ == call_index ? callables() : void()), ...);
                        ^ ~~~~~~~~~~~   ~~~~~~
