Update ssh-probe to advertise v2 Protocol
Everytime wassh connects to a machine it first uses ssh-probe to see if the machine is actually reachable.
There's a nice encoded version string SSH-1.5-CERN_wassh
that used to generate this warning in /var/log/secure:
Aug 22 15:41:51 lxfsre58c02 sshd[14795]: Protocol major versions differ for 188.184.29.245: SSH-2.0-OpenSSH_5.3 vs. SSH-1.5-CERN_wassh
This version string gets updated to SSH-2.0-CERN_wassh
and we get rid of the warning.
