lib/efi: Add support for loading the initrd

When loading non-efi tests with QEMU's '-kernel' option we also load
an environ with the '-initrd' option. Now that efi tests can also be
loaded with the '-kernel' option also provide the '-initrd' environ.
For EFI, we use the EFI_LOAD_FILE2_PROTOCOL_GUID protocol to load
LINUX_EFI_INITRD_MEDIA_GUID. Each architecture which wants to use the
initrd for the environ will need to call setup_env() on the initrd
data. As usual, the new efi function is heavily influenced by Linux's
implementation.
