[PATCH v2] classes/initramfs: Print messages in case of a build error

[Quirin Gylstorff]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

This patch eases the fault analysis in case of a broken
initramfs generation.

This prints the messages from 'update-initramfs' instead of:

```
Available versions:
Nothing to do, exiting.
ERROR: No initramfs was found after generation!
```
