Use hash for ControlPath instead of full variables

The generated socket path can be too long, if your FQDN is very long...

Typical error message from ssh client:
unix_listener: path "/tmp/ssh-fqduawon/master-USER@HOST:PORT.qfCZ51OAZgTzVLbg" too long for Unix domain socket

Use a hashed version instead, to keep within the socket file path limit.

This requires OpenSSH_6.7p1, or later.
