Save node binary with name flipper-runtime

Summary:
As discussed with lblasa. This solves a few issues:

- Confusing names in `ps` and Activity Monitor related to Flipper.
- Permission requests for the Keychain from "node" lead users to deny it.
- Seeing "node" as allowed apps for an entry in Keychain is confusing.
