modalDialog: Replace Shell.Stack with layout manager

Commit e98eb57e3e8b added flags to expand the dialog's background
stack, which works fine with the current clutter-1.16 branch, but
breaks on clutter-1.14 (as shipped with GNOME 3.8).
Using an St.Widget with a Clutter.BinLayout fixes this, and is more
modern Clutter usage.
