Merge profiles: add a profile for hwctl

I'm working on a Rust library project that collects hardware and OS information from the local system and queries the Ubuntu Hardware Certification service to determine if the device model has been certified.

I'd like to add an AppArmor profile to ensure the `hwctl` program has access to the resources it needs.
