base-sms: wait up to 60s when sending SMS messages

The operation sending the raw data of the SMS may timeout because the current value of 10s is too low.

When this happens, we may end up marking the modem as invalid if the operation takes much longer, as in #133 (closed)

So, update the raw data sending timeout to a much longer value.
