package/qt5declarative: move the qt5gui select from qt5declarative to qt5quick

As requested/suggested by Sergey Kuzminov([1]) move the qt5gui select from
qt5declarative to qt5quick.

The qt5declarative (without qt5quick) compiles and installs fine without
qt5gui enabled and code inspection of the qt5declarative souce package *.pro
files shows the unconditionally gui dependencies only in for doc-snippets
and/or test projectes or real the qt5quick moduls.
