This patch reinstate the logic which was present originally in WebKit but
later remove, it is meant to handle the scenario 'repeatingDuration' is not
a multiple of 'simpleDuration'.

(SVGSMILElement::calculateAnimationPercentAndRepeat): Update to handle multiple of 'simpleDuration'
* LayoutTests/imported/w3c/web-platform-tests/svg/animations/animate-fill-freeze-with-repeatDur-expected.txt: Rebaselined
