Modified SSH to clear askpass environment if no prompter is available.

Cygwin-based SSH distributions include a default GUI-based askpass, but it
is confusing and doesn't provide any context or even prompt! When running
the daemon in the default Cygwin/MinGW environment, this askpass was being
invoked. It's better to just avoid that.
