Add a VTY command which deletes all expired SMS.
We already delete SMS which have been sent successfully. However, there
are plans to accept SMS for any subscriber in order to fix the problem
described in https://osmocom.org/issues/2354 ("SMSC: Store&Forward not
working for subscribed but unregistered MS").
This means we may end up storing SMS which never get sent, e.g. because
the B subscriber doesn't actually exist. This could lead to a higher
degree of SMS database growth over time, and therefore we need a way
to keep database size under control.
As a first step, introduce a DB function which removes an expired SMS,
and add a VTY command which removes all expired SMS from the DB.
Later commits will build upon this to remove expired SMS automatically.
The SMS expiry time period is currently hard-coded to 2 weeks.
We could make this configurable in the future if desired.
