x/crypto/ssh: 'no common algorithms'

[tobor]

ssh: handshake failed: ssh: no common algorithm for client to server cipher; client offered:
[aes128-ctr aes192-ctr aes256-ctr aes128-gcm@openssh.com arcfour256 arcfour128]
server offered:
[3des-cbc aes128-cbc aes192-cbc aes256-cbc]

The same mistake:
#12982

You have to enable the insecure cbc algorithms manually by patching x/crypto/ssh. Merged into #12982.
