    testing: more authentication tweaks

    ikev2: some authentication log cleanups
    
    - drop some redundant log lines; notably:
        Digital Signature authentication using %s failed in %s
      (should the "authenticated using ..." log line include this
       trivia or is that just too much information and all that
       matters is that it was authenticated?)
    - prefix with "authentication failed: "
    - log with RC_LOG_SERIOUS
    
    (but ignore anything connected to pre-shared-key)

    crypto: don't be subtle about who generates the signature authenticated log line
    
    These generate the authenticated log line:
      v2_check_auth()           -> v2_authsig_and_log()
      check_signature_gen()     -> authsig_and_log_using_pubkey()
      ikev2_verify_ecdsa_hash() -> v2_authsig_and_log_using_ECDSA_pubkey()
      ikev2_verify_rsa_hash()   -> v2_authsig_and_log_using_ECDSA_pubkey()
    These do (should) not:
      ikev2_verify_rsa_hash()   -> v2_sigauth_using_RSA_pubkey()
      ikev2_verify_ecdsa_hash() -> v2_sigauth_using_ECDSA_pubkey()
      try_signature_fn          -> sigauth_using_pubkey_fn
    Which makes it hard to miss:
      if (!authsig_and_log*())
         log(exactly the same error)
