fix: remove ALSA udev rules to resolve build issue

- Remove services.udev.packages with alsa-utils (causing udev rules conflict)
- Keep services.pipewire.alsa.enable for ALSA compatibility
- Re-enable alsa-utils in system packages for testing utilities
- ALSA compatibility maintained through PipeWire, not udev rules
