check_ssh: check protocol

It would be useful to be able to detect the protocols supported by the remote
ssh server to locate any using the insecure ssh v1 protocol. This patch
attempts to match against the protocol string in the ssh response.

Example:

check_ssh -H my.host.com -P 2.0

check_http: Don't let "-N" expect an argument

Fix the problem that check_http's "-N" option expects an argument
although it shouldn't.  The corresponding long option ("--no-body")
wasn't affected.

This error was introduced in ee3c4014d511e105489b081390636cacd4c53e3f.
Thanks to Kerry Hughes for reporting it on the devel@ list.
