telephony: Increase the Send SMS retry delay timer

When the device is registered to the network,
framework will start resending the SMS. Number of
retry is 3 and the retry interval is 2seconds.
Since the retry interval is very less, some of
the SMS are never sent out. Failure may be
due to modem busy with SIM files caching or
service center busy etc.

This patch increases the SEND_RETRY_DELAY to
10seconds.
