Add exception filter for _sqlite_dupe_key_error

We can get 'PRIMARY KEY must be unique' error on some
platforms and versions of sqlite library while trying to
insert the row with the same primary key that already exist.
In this case oslo.db should raise DBDuplicateEntry error.
Add corresponding filter to _sqlite_dupe_key_error

Closes-Bug: #1386145
