[webkit-qt] [week 30] Qt 5 version update

[Osztrogonac Csaba]

Hi All,

Qt5 update is coming soon ... ;-)

Last Qt 5 update for WebKit trunk was long time ago, it's time to update again.
Now the latest Qt 5 hash is 654fcc335c20431f60d3fde32e636aae38afe658, it seems
it works fine. (WK1,WK2, API tests, layout tests)

I'm going to update Qt 5 on the bots soon (in 2-3 hours), and then land the necessary
buildfix (by Simon) in https://bugs.webkit.org/show_bug.cgi?id=91822 (already r+ -ed.)

br,
Ossy
