main/qtwebbrowser: add missing dependencies
When qt5-qtquickcontrols
and qt5-qtgraphicaleffects
are not installed, qtwebbrowser
shows a blackscreen at start and prints errors comparable to module "QtQuick.Controls.xxx" is not installed
and module "QtGraphicalEffects" is not installed
.
Hope I didn't miss anything, MR was tested on Phosh in QEMU.
