Now that we added special handling to the C files in libstub, move the one remaining arm64 specific EFI stub C file to libstub as well, so that it gets the same treatment. This should prevent future changes from resulting in binaries that may execute incorrectly in UEFI context. With efi-entry.S the only remaining EFI stub source file under arch/arm64, we can also simplify the Makefile logic somewhat.
