Build failure: udev-rules on latest nixpkgs-unstable

[slotThe]

Starting from 41d38a5aa5629562a424717665f3349c5fc1f27a (#367733), my configuration fails to build udev-rules, since apparently cat can't be found:

Checking that all programs called by absolute paths in udev rules exist... FAIL
/usr/bin/cat is called in udev rules but is not executable or does not exist

No one in maintainers, so pinging @ck3d because of #367733

[ck3d]

I created a PR which fixes the path to /usr/bin/cat, but I did not test if the udev rule checker passes. Could test the PR?

[ck3d]

I tested the PR successfully by adding alsa-utils to NixOS option services.udev.package.

[cmm]

There is a(n arguably) more general and future-proof fix here: #370740
