ssh: add ServerConfig.ServerVersion option
The SSH server does not allow for setting a version string in the same
manner as the client. This update adds a ServerVersion member to the
ServerConfig structure which when set, causes the server to use that
member instead of the default version string. This allows building
an golang based SSH server which can present any version string
the user wishes.
It also adds an else statement to the client assignment of the
ClientVersion to avoid an allocation when using a user defined
ClientVersion.
