feat(libSceVideoOut): keep key presses from the title's keyboard while a dialog is shown

KeyboardInput no longer publishes a key press to libSceKeyboard while a modal dialog
captures input, so the keys that answer the dialog are not also typed into the
title. Key releases still reach it. keyboard_tests links libSceIme because it
builds KeyboardInput.cpp itself.
