EFI stub: add StubInfo if non-existant

Browse Source 
currently if a stub image is directly booted, bootctl reports:
```
Current Loader:
      Product: n/a
          ESP: /dev/disk/by-partuuid/b0a0807d-0592-40e9-adac-3bb724e9e305
         File: └─/EFI/Secure/secure-boot-4.14.8+.efi
```

Let's add a StubInfo which will be displayed by bootctl too (in a later
patch).
