smscb: Always start ETWS timer even in cells without ETWS support

ETWS is sent over both dedicated channels and broadcast channels. Some BTS models may not support the latter, but it is still useful to start the related timer to ensure bts->etws.active gets set to false after the emergency period has concluded.
