[Buildroot] Disable qt5declarative dependency on GUI

[Buildroot] Disable qt5declarative dependency on GUI

Hello. My English is poor. You need to remove the "select 
BR2_PACKAGE_QT5BASE_GUI" dependency from the 
package/qt5/qt5declarative/Config.in file.

This is needed to build Qt console applications without a GUI. The 
qt5declarative library is needed as a replacement for the outdated 
qt5script.

Some aspects of qt5declarative are not GUI related: 
https://doc.qt.io/qt-5/qjsengine.html

A simple example:

QJSEngine myEngine;
QJSValue three = myEngine.evaluate("1 + 2");

Thanks a lot!

Just sent out an improved version of your patch (instead of removing the qt5gui
select entirely move it down to the qt5quick section) to the mailing list (see [1])...

Thanks for suggestion!

Regards,
Peter
