dump failed key and signature

This will log the failing key and signature.

You can convert the key to an OpenSSL PEM format key using something

ssh-keygen -ef /path/key.pub -m pem

Verifying the contents of the signature blob is more difficult. Some
extra debug logging in ssh-rsa.c might be required there
