ssh/agent: return an error for unexpected message types

Previously, receiving an unexpected message type in response to a key
listing or a signing request could cause a panic due to a failed type
assertion.

This change adds a default case to the type switch in order to detect
and explicitly handle unknown or invalid message types, returning a
descriptive error instead of crashing.

Fixes golang/go#75178
