Check the SSH server in a way that complies with the SSH protocol using x/crypto/ssh. This change fixes lima-vm#4334 by falling back to usernet port forwarder on failing SSH connections over VSOCK. - pkg/networks/usernet: Rename entry point from `/extension/wait_port` to `/extension/wait_ssh_server` Because it changed to an SSH server-specific entry point. When a client accesses the old entry point, it fails and continues with falling back to the usernet forwarder. - pkg/sshutil: Add `WaitSSHReady()` WaitSSHReady waits until the SSH server is ready to accept connections. The dialContext function is used to create a connection to the SSH server. The addr, user, privateKeyPath parameter is used for ssh.ClientConn creation. The timeoutSeconds parameter specifies the maximum number of seconds to wait. Signed-off-by: Norio Nomura <norio.nomura@gmail.com>

This change changes the SSH server keys that have been generated for each boot in guest OS to be generated by hostagent for each boot. This allows the hostagent to obtain the public key before booting, so that knownhosts can be used with an ssh connection. The code that uses `ssh.InsecureIgnoreHostKey()` in `x/crypto/ssh` is pointed out in CodeQL as `Use of insecure HostKeyCallback implementation (High)`, so it is an implementation to avoid this.
