dev-qt/qtwebengine: quick fix for build race conditions (qt6)

Done as two separate patches given one is a chromium backport
(fixed in 6.8), and the others are qtwebengine-side issues.

Thanks to Matt Whitlock for testing.

Quite possible there are more issues, but there is no harm in
fixing the ones we know about so far.
