Bump the version of the SQLite caches

Browse source 
This avoids problems with older versions of Nix that don't put the
caches in WAL mode. That's generally not a problem, until you do something like

  nix build --print-out-paths ... | cachix

which deadlocks because cachix tries to switch the caches to truncate
mode, which requires exclusive access. But the first process cannot
make progress because the cachix process isn't reading from the pipe.
