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.
