efi_loader: fix building aarch64 EFI binaries
While our EFI binaries execute without problems on EDK II they crash on
a Lenovo X13s. Let our binaries look more like what EDK II produces:
* move all writable data to a .data section
* align sections to 4 KiB boundaries (matching EFI page size)
* remove IMAGE_SCN_LNK_NRELOC_OVFL from .reloc section flags
