mesa-vpu: move Mesa runtime + diagnostics package list to configng mid tier

Second phase of the mesa-vpu → configng migration (first phase:
Hook 1 overlay + Hook 3 browser, commit deb764d).

The package list in post_install_kernel_debs__3d (libgl1-mesa-dri,
libglx-mesa0, mesa-utils, mesa-vulkan-drivers, vulkan-tools, and the
four glmark2-{,es2-}{wayland,x11} flavours) is DE-agnostic desktop
GPU-runtime content. Moving it to armbian-configng's common.yaml
mid tier (configng commit f175558d) means every mid-tier desktop
install gets the same set, whether it's an image-build going through
module_desktops mode=build or a runtime install on an already-booted
minimal image via armbian-config.

Three phantom entries from the original list were dropped on the
configng side and also removed from this hook:

  mesa-utils-extra   — no such binary package in any Debian/Ubuntu
                       release (archive dropped it years ago)
  glmark2            — source package only; only the
                       -{wayland,es2-wayland,x11,es2-x11} binaries ship
  glmark2-es2        — same, no binary package ships under that name

apt has been silently skipping them on every mesa-vpu run with
'E: Unable to locate package', cluttering logs without affecting the
build outcome.

What remains in post_install_kernel_debs__3d after this trim is
genuinely build-framework-only territory — things configng
(RELEASE × ARCH keyed) can't express because they need
LINUXFAMILY × BRANCH awareness:

  - rockchip-rk3588 / rk35xx + noble + vendor conditional rockchip
    multimedia PPA (liujianfeng1994/rockchip-multimedia), with its
    rockchip-multimedia-config / libv4l-rkmpp / gstreamer1.0-rockchip /
    libwidevinecdm0 payload
  - libv4l-0 pre-req install (precedes rockchip-multimedia)
  - KDE Neon base-files hold/unhold workaround
  - noble/oracular arm libdav1d7 hold/unhold
  - final dist-upgrade pass (to pick up whatever the PPAs shift)

The install call is now gated on `pkgs` being non-empty so non-rk3588
boards don't invoke apt with zero package names.
