games-puzzle/xblockout: mark as C17, lift sed to patch

Game uses recursive calls to variable lenght function walkrowcol,
it's called with 1, 2, 3, 4, and 6 argument callback to operate
on buttons. Best to leave it as it instead of possibly-buggy code
duplication and calling specialized variants on each callsite.
