Fix for ecdsa agent pub key auth

[Yury Korolev <yurykorolev@xxxxxx>]

Hi,

I was trying to use ecdsa key with agent auth and get error:

ssh_packet_socket_callback: packet: read type 60 [len=140,padding=7,comp=132,payload=132]

ssh_packet_process: Dispatching handler for packet type 60

ssh_userauth_agent: Public key of id_ecdsa accepted by server

ssh_key_algorithm_allowed: Checking ssh-ecdsa with list <ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-rsa,rsa-sha2-512,rsa-sha2-256,ssh-dss>

ssh_userauth_agent_publickey: The key algorithm 'ssh-ecdsa' is not allowed to be used by PUBLICKEY_ACCEPTED_TYPES configuration option

ssh_userauth_agent: Server accepted public key but refused the signature

I think, this commit misses agent pubkey auth part:

Patch is attached.
