thelounge: fix sqlite logging
Previously, we never actually built the SQLite binding, causing The Lounge
to bail when attempting to load SQLite logs [0]. It wasn't caught before
because it wasn't thrown fatally, for whatever reason. Perhaps we should
fix this in the future with a patch and/or more robust tests, but for now,
let's just fix the issue.
