fix: persist diagnostics opt-in inside containers for addon telemetry

- install.func + alpine-install.func: create /usr/local/community-scripts/diagnostics
  inside the container when DIAGNOSTICS=yes (from build.func export)
- Enables addon scripts running later inside containers to find the opt-in
- Update init_tool_telemetry default type from 'tool' to 'pve'
