Implement WifiNetworkSpecifier#redact.

This is needed so that if an app files a NetworkRequest or
NetworkCallback with a WifiNetworkSpecifier and null UIDs,
sensitive information is redacted. Otherwise, the request could
match WifiNetworkAgentSpecifier of a connected wifi network, and
thus learn if a network is available that matches the specifier
it constructed.
