[PATCH master 2/5] filetype: introduce separate filetype_x86_efi_linux_image

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

I originally suggested adding only filetype_x86_linux_image during
review, because I was eyeing removal of the EFI types for the other
architectures in favor of handling the EFI stub differently.

I am not pursuing this further, so let's add filetype_x86_efi_linux_image
as it will simplify code at a number of places in following commits.
