Move i386/efi files to new home in efi/loader/arch/i386

This was not (and still is not) connected to the build, but the EFI
loader is in the process of being built for other than amd64 so these
files ought to live in their eventual MD location.

EFI boot loader for FreeBSD/i386.

Doesn't boot a kernel yet, but it can read an ELF file from the EFI FAT
partition.
