fail hard and stop if dtb-file cannot befound

I am testing a new device on a mainline kernel.

During that I have made a mistake and entered the wrong name/path for the dtb.

However, boot-deploy as called by pmboostrap install did not stop on this error below:

16:46:53.288075 == Using boot-deploy to finalize/install files ==

I would expect that in this situation would stop the pmboostrap install running and notify the user of the error.

If this is actually not a boot-deploy issue, but a pmboostrap issue, please move it.
