For all 120 differences.

(We can also report the number of correct key bytes as well but based on my observation it doesn't provide a lot of information.)

@vogelpi, fyi.

[ceca] Report number of correctly guessed key byte differences

This number is a actually a far more relevant indicator for the amount
of leakage in the traces than successful key recovery (pass/fail).
Therefore, this commit adds the functionality to compute this number and
report it on the command line.

This addresses lowRISC#30.
