Check if valid kernel and/or FS

[Benoit RAT]

Thanks,

I want to know, if i am using the default environment (the that I am using
from compilation)
barebox> no valid environment found on /dev/env0. Using default environment

Or I am using the one that there is in /dev/env0

It is in the case someone break something in the NAND flash env, I want to
save again the default one.
