Subject: [PATCH] luv-live-image: Mark boot partition as EFI System Partition
 (ESP)

Per the UEFI specification the correct system type (in fdisk parlance)
or OSType (in the UEFI spec) field value is 0xEF for the EFI System
Partition (ESP).

Instead of marking the boot partition as FAT32 (0xC) use fdisk to mark
it as 0xEF. Note that we can't use parted for this since it doesn't
have an option to mark a partition as an ESP.
