qtwebkit-examples: add missing RDEPENDS for qmlplugins

Some examples require qtwebkit-qmlplugins (flickerview, youtubeview),
and this dependency is not automatically added. Without this patch,
and without manually adding qtwekbit-qmlplugins, we get errors like
this:

qrc:///flickrview.qml:42:1: module "QtWebKit" is not installed
