Subject: Move grub files from /EFI/BOOT/ to /boot/grub/ on ISO 9660

Move the location of GRUB files so that there is boot-platform
(BIOS vs EFI) neutral place for GRUB-specific files (e.g. configuration
files, background images, etc.).

The EFI binaries are obviosly staying in the default/fallback boot path
`/EFI/BOOT/BOOT*.EFI`, otherwise there will be no UEFI booting.

The /boot/grub/ directory will be used to store BIOS (i386-pc) GRUB
bootsector images, if we get to that.

It is also a requirement for implementing `loopback.cfg` support, since
the file's path must be `/boot/grub/loopback.cfg`.

Implements #206
