Since old SQLite versions do not have sqlite3_errstr(),

provide a dummy fallback implementation.
Do not bother to decode the error, SQLite error codes
are not useful enough for that to be worthwhile.
Note that using sqlite3_errmsg(db) would be a bad idea:
On malloc() failure, db is NULL, which would cause a segfault.
Issue noticed by kristaps@.
