sql: account DDL changes as 0 or 1

The original SQLite doesn't account DDL changes at all. Such changes
simply do not update the sqlite3_changes() return value. But iproto
clients want to know a result of DDL operation, particularly for
IF [NOT] EXISTS DDL operations.

We cannot return real count of affected tuples, because it depends on
the tarantool version. For example, now DROP TABLE deletes tuples from
_space, _index, _truncate and _trigger. But in the future this set of
system spaces can be changed.

With considering the above remark, lets return always for all DDL
operations either 0, if nothing happened, or 1, if something was
created, deleted or modified.
