fix(#1111): drop rusqlite bundled feature — use system libsqlite3

rusqlite was compiled with features=["bundled"] which embeds the
SQLite C source and compiles it via the cc crate on every fresh
dependency build. libsqlite3 is already in nativeBuildInputs (pkgs.sqlite
+ pkgs.pkg-config) so the system library is always available in the
nix sandbox. Dropping bundled removes the C compilation step from
the dep tree.
