Fix warning in tst_qfuture 

Explicitly move the argument into the return value to silence:

qfuture_impl.h:153:20: warning: local variable 'arg' will be copied
despite being returned by name [-Wreturn-std-move]
            return arg;
                   ^~~

[...]
qfuture_impl.h:153:20: note: call 'std::move' explicitly to avoid copying
