Support findiso=

[Ryan Finnie]

These format allows you to specify a path to an ISO where the CD is, rather than a block device. It'll scan block devices, mount them, then look for the specified filename and mount it loopback.

Example GRUB2 entry:

menuentry "Finnix" {
  insmod part_msdos
  insmod ext2
  set root='(hd0,msdos1)'
  search --no-floppy --fs-uuid --set=root 78a8f4d9-1462-4696-9577-9a10d0056b3b
  loopback loop /home/ryan/finnix-neale.iso
  linux (loop)/boot/x86/linux64 findiso=/path/to/finnix.iso vga=791 quiet
  initrd (loop)/boot/x86/initrd.xz
}

Turns out there are a good dozen or so variations of this functionality, each with a different name. I've decided to standardize on one format (findiso=), otherwise Finnix would be expected to support them all.
