Change dependency of obmc-console-ssh.socket to obmc-console

Restart obmc-console will cause restarting of obmc-console-ssh.socket.
obmc-console-ssh.socket restarting sometimes failes with
"Address already in use" error.
If changing dependency from 'Requires' to 'Wants', restarting
obmc-console will not cause restarting of obmc-console-ssh.socket.

Resolves openbmc/obmc-console#7
