Remove timeout for http.Client in registry/client/repository.go.

Timeouts should not be a discrete period of time, because they end
up being arbitrary and may be difficult to gauge correctly against
very large Docker layers. Rather, timeouts should be set at the
transport level using the SetDeadline attribute on a net.Conn
object.
