Subject: [PATCH] add part_apple to EFI rescue image to fix missing prefix

On Mac rescue image is booted from HFS+ partition, so bootpath looks like
/ACPI(a0341d0,0)/PCI(1,1f)/ATAPI(0,0,0)/HD(3,5d1,ca3,0000000000000000,20,0)/EndEntire

grub fails to find device for this path because it cannot scan partition
table. The simplest fix is to add part_apple by default.
