CodeQL Bundle: Precompiled queries have mode 0600

The precompiled queries in the CodeQL Bundle (e.g., v2.19.1) have file permission `0600`; i.e., read-writable by the file owner only. This causes the CodeQL CLI to be unable to read the precompiled queries when it's run as a different user, which starts a lengthy compilation process.

This can be resolved with `chmod go=u`, but it would be handy if the bundle was shipped in this state.
