Support making a Fedora 9 usb stick for the Intel-based Macs
We didn't set up the live image for EFI booting in Fedora 9, but all the
pieces are there. So add something that will work for the stock Fedora 9
images

commit ceb818924b458b273293b17dd54b482b4581b528

Add support for booting Intel Macs via EFI on USB (#450193)
Intel Macs require an EFI setup for booting off of USB, so add support
to the creator and iso-to-disk for handling this. Main components are
*) Adding EFI grub bits to the image
*) Creating a grub.conf in addition to the syslinux config
*) Doing the appropriate munging when copying over
NOTE: The first time you create a bootable USB stick for a Mac, it will be
a destructive operation due to the need to switch from msdos -> gpt
