[PATCH] contrib/ssh-copy-id: do not use shared connection

[Konstantin Khlebnikov]

ssh-copy-id always needs new connection to the server when it
evaluates its version and tests if the key is already installed.
Before this patch ssh-copy-id might reuse existing shared connection
and hang in REMOTE_VERSION=(...) because it get interactive connection
which never ends. Also it will think that the key is already there
because connection using it is succeed.

This patch adds option "ControlPath=none" into command line and remote
command "exit" to be sure that test connection never hangs.
