efi_loader: Add mem-mapped for fallback

Browse Source 
When we don't have a real device/image path, such as 'bootefi hello',
construct a mem-mapped device-path.

This fixes 'bootefi hello' after devicepath refactoring.

Fixes: 95c5553ea2 ("efi_loader: refactor boot device and loaded_image handling")
