Increase the default timeout from 30 to 60 seconds.

The DEFAULT_WAKE_LOCK_TIMEOUT should be longer than the timeouts
of the vendor ril, aka. rild. We are seeing timeouts which are
30secs and possibly longer. An alternative would be to add
TelephonyManager.PROPERTY_WAKE_LOCK_TIMEOUT for but I feel a 60
second default is appropriate for all platforms.
