Do not migrate NetworkPrediction preference on Android.

Do not migrate NetworkPrediction preference on Android.

Do not call chrome_browser_net::MigrateNetworkPredictionUserPrefs() on Android,
because preference migration from kNetworkPredictionEnabled to
kNetworkPredictionOptions is carried out by some platform-specific code on
Android.

Nit: Instead of "after some time", could you define an objective criterion here?
That way, even if you and me forget about this, someone else who comes across
this code can do the cleanup.
