workflows: tools: build natively instead of in docker container

The pre-built thesofproject/sof docker image carries an older
alsa-lib / alsa-utils that no longer matches the versions required to
build the current SOF user-space tools (in particular alsatplg used by
the topology2 build). This patch moves the user-space tools build off
docker and build it directly on the ubuntu-24.04 runner.

  - install the toolchain via apt
  - bootstrap autoconf 2.72 (Ubuntu 24.04 ships 2.71)
  - build the SOF forks of alsa-lib and alsa-utils at the same pinned
    commits used by testbench.yml
  - run scripts/build-tools.sh with PKG_CONFIG_PATH / LD_LIBRARY_PATH /
    PATH pointed at the freshly built ALSA tree

The SOF-alsa-plugin job in the same workflow was already native and is
left unchanged. The only consumer of this reusable workflow
(daily-tests.yml) is unaffected by the internal switch.
