lib/efi_loader: fix ABI in efi_mm_communicate_header
Pack struct efi_mm_communicate_header as done in EDK2 as seen in
release 201808 [1]. If not packed sizeof() for the structure adds
4 additional bytes on 32bit targets which breaks the ABI.

Fixes: 23a397d2e2fb ("efi_loader: Add headers for EDK2 StandAloneMM communication")
