Generic/OpeningFunctionBraceKernighanRitchie: fix error position

The `SpaceBeforeBrace` error code is about the space before the scope opener, but was being thrown on the parenthesis closer preceding it, which could be confusing when there is a type declaration between the two.

Fixed now.

I haven't added a test as no meaningful test can be added as the error "column" is not part of the test logic.
