alsa-ucm-conf: 1.2.12 → 1.2.13-unstable-2025-03-21; validate in alsa-lib

[illdefined]

Switch alsa-ucm-conf to rolling release.

Updates to the UCM configuration files are released in tandem with the ALSA library every half year or so.

The UCM configuration files however receive frequent updates with new profiles for additional hardware and I believe that users would benefit from making these available in nixpkgs independently of the ALSA lib release cycle.

The configuration files are validated automatically by upstream after review and so I don’t expect this to break very often.
Just to make sure, I added validation of the UCM configuration to alsa-lib, as part of installCheckPhase.
