package/duktape: move submenu

Since the introduction of duktape in [1]. This package has been present
under the "JavaScript" sub-menu.

This sub-menu was mostly used for JS libraries and programs so duktape
should have been under the "Interpreter languages and scripting"
submenu.

Since duktape is now the only entry in the JavaScript submenu, move this
package to a better suited place and remove the JavaScript submenu.
