housekeeping: removal of menu items for no longer available addons

- removal of EX-addonsvc.menu entry in config/menu/ as the lfs file for this could not be
   found in the IPFire git repo all the way back to CU30
- removal of EX-addonsvc.menu, EX-asterisk.menu and EX-bluetooth.menu which are no longer
   in IPfire for two years or longer.
