unstrip: Add various checks for bad input data

eu-unstrip was clearly not written for bad ELF input files. Not surprisingly
because it would be slightly odd to run it on untrusted input, which wasn't
just stripped in two.

But I have added a couple of robustness fixed that should at least not make it
crash and give an error message that will hopefully explain what is wrong with
the input files.
