Incorrect dialog text in 'select_util' function

The select_util function in setup-disk uses vfat_msg for its main dialog text (above the menu), but that text is for a different situation (English text: "EFI system partition detected. Vfat required to create bootable EFI partition.").

The text should be something like "Please select your desired disk utility:", but nothing like that seems to exist anywhere, so this is likely a very old issue (and easy to overlook since most people, including myself until today, only pay attention to the menu text).
