boot1.efifat: provide a fallback startup.nsh

In case the firmware falls through to executing startup.sh, populate it
with the name of our boot loader. In normal operation this should not be
necessary but may allow the system to boot if it would otherwise just
remain at a shell prompt.

Add a FAT label to the EFI boot1 partition.

Update comment: only one file in the FAT file system EFI boot image

Sponsored by: The FreeBSD Foundation

Revert to FAT12. This file system is apparently too small for FAT32, even
if the old (pre r264889) newfs_msdos allowed it. And FAT12 seems to work
perfectly well.

Apparently this is supposed to be FAT32, not FAT12.

Add generation of an EFI filesystem to hold boot1.efi. This is a near-exact
copy of the code from boot1.chrp again.

The resulting image is installed to /boot/boot1.efifat. If dd'ed to an 800K
"efi" partition, it should result in a bootable system.
