build: update planner build for sqlite3 (#12228)

refs: https://github.com/Agoric/agoric-private/issues/504

## Description
Updates the build scripts for ymax-planner in order to add some files that the new sqlite3 kv-store requires.
Without this the planner crashes because the `better-sqlite3` package does not find the files it expects

### better-sqlite3 requirements
- bindings file: a build file that is created by better-sqlite3 and needed independent of the final `entrypoint.js` build
- node_modules: better-sqlite3 requires package.json/node_modules to identify the root directory of the package.

### build scripts
the build script is also updated since we need to mount a directory for sqlite db in order to make it persistent across restarts

### Testing Considerations
tested out by running test containers on GCP
generated image: https://github.com/agoric/agoric-sdk/pkgs/container/agoric-sdk/577293600?tag=ymax-planner-test


### Upgrade Considerations
The build scripts have been updated in the this PR and ymax planner must not be deployed without it
