[general] Remove the last bits of gnu-efi

Browse Source 
With the new bootloader changes that use clang to directly build an EFI
application, the last piece of GNU-EFI that was used (the linker script)
is no longer necessary.

Thanks for being a great starting point, GNU-EFI!

## GNU-EFI
jsix's UEFI bootloader initially used [GNU-EFI][], and still uses one file (the
linker script for the bootloader) from that project. GNU-EFI claims to be
released under the BSD license. Again, I could not find its specific license
file, so I am reproducing a generic 3-clause BSD license (the most restrictive,
so as not to assume any extra rights that may not actually be granted) for it
