Bill Richardson 2f6a71fb34 Handle short read error correctly in vbutil_kernel.c ...

If you try to read a file that's all zeros, it tries to read a zero-length
kernel blob, fails to do so (or suceeds with an empty result, depending on
your point of view), and prints

  ERROR: Unable to read kernel blob from <file>: Success

That's not very helpful.

This change makes it say

  ERROR: No kernel blob found

instead.
