Pekka Enberg 31308f3699 core: Switch SQLite to use locking_mode EXCLUSIVE ...

Let's switch the SQLite benchmarks to use similar file locking protocol
as we do. Improves SQLite's performance by 2x, but Limbo is still
faster.

Before:

rusqlite/Prepare statement: 'SELECT * FROM users LIMIT 1'
                        time:   [2.1027 µs 2.1239 µs 2.1563 µs]
                        thrpt:  [463.75 Kelem/s 470.83 Kelem/s 475.57 Kelem/s]

After:

rusqlite/Execute prepared statement: 'SELECT * FROM users LIMIT 1'
                        time:   [940.07 ns 944.16 ns 949.39 ns]
                        thrpt:  [1.0533 Melem/s 1.0591 Melem/s 1.0638 Melem/s]
