- disable the autoupdater if running as mas (was not working anyway, just logging an error on every start)
- replace check via app.requestSingleInstanceLock() with LSMultipleInstancesProhibited in Info.plist

- "asarUnpack": "**/*.node" to also sign the native addons when packaging
- add the required mas-specific entitlements which include the app-sandbox key
