uefi-common: install firmware-sof-signed on every UEFI build

[igorpecovnik]

UEFI boards are predominantly x86 laptops where audio routes through SOF. Without the firmware blobs the kernel SOF driver probes, fails to load `/lib/firmware/intel/sof-ipc4//sof-.ri`, and the internal speakers / analog path stays silent (HDMI still works — many users don't notice until they unplug).

Move `firmware-sof-signed` from the per-release CLI baseline to the UEFI family include — that's the right home for a desktop-/laptop-leaning firmware package.

Pairs with

• cli/amd64: drop firmware-sof-signed from trixie + sid #9855 — drops `firmware-sof-signed` from `config/optional/architectures/amd64/_config/cli/{trixie,sid}/main/packages`. After both merge, the package is shipped on UEFI builds (covers most of the population that needs it) but no longer pulled into non-UEFI / SBC CLI/amd64 images.

Why unconditional (not gated on `LINUXFAMILY=x86`)

`firmware-sof-signed` is `Architecture: all` — same .deb on every arch, ~7 MB of blobs. Adding it for arm64 UEFI as well is cheap and keeps the file simpler.

Test plan

• Build a UEFI x86 image — `dpkg -l firmware-sof-signed` shows installed; `ls /lib/firmware/intel/sof-ipc4/lnl/` is non-empty
• Boot on a Lunar Lake / Meteor Lake laptop — `dmesg | grep -i sof` no longer reports "Direct firmware load … failed"; `aplay -l` lists the SOF card
• Build a UEFI arm64 image — no apt error (package is arch-all and resolves cleanly)

Release Notes

• Chores
  • Updated UEFI firmware configuration to ensure the signed Intel Sound Open Firmware (SOF) DSP package is included in all builds, improving system compatibility and stability.

Poem

🐰 I nudged a line into the boot-time song,
where DSP dreams hum loud and strong.
A signed blob tucked into the frame,
UEFI wakes to Intel's name.
Hop, patch, and listen — all systems belong.
