Add `libsqlite3-sys` crate to avoid sqlite3 missmatching version.
From [https://lib.rs/crates/libsqlite3-sys](https://lib.rs/crates/libsqlite3-sys)
> If you use the bundled feature, libsqlite3-sys will use the cc crate to compile SQLite from source and link against that. This source is embedded in the libsqlite3-sys crate and is currently SQLite 3.30.1 (as of rusqlite 0.21.0 / libsqlite3-sys 0.17.0). This is probably the simplest solution to any build problems.
Remove sqlite OS packages dependencies for build.
Also, we fix a format error to allow CI tests to pass again.
