Awaiting a possible improvement of the integration, I'd suggest that budgie-desktop-environment installs the file:
/usr/share/budgie-desktop/applications/ibus-setup.desktop
with the same contents as
/usr/share/applications/ibus-setup.desktop
except that the line
NotShowIn=GNOME;Unity;
is replaced with
OnlyShowIn=Budgie;
That way IBus Preferences would show up in the menu.
