io-uring not enabled in Linux mediasoup-worker prebuilt since it uses kernel 5.15

[ibc]

In mediasoup-worker-prebuild CI job we are using an old Ubuntu version 20.04 to create the Linux mediasoup-worker prebuilt binary (for reasons as documented inline). Problem is that Ubuntu 20.04 uses kernel 5.15 (<6) so we are not enabling io-uring on these binaries :(

# For Linux let's use an old version of Ubuntu (20.04) that builds the
# mediasoup-worker binary using an old version of GLib, so it will work
# on Linux hosts running more modern GLib versions.
# See https://github.com/versatica/mediasoup/issues/1089.
- os: ubuntu-20.04
  cc: gcc
  cxx: g++
- os: macos-12
  cc: clang
  cxx: clang++
- os: windows-2022
  cc: cl
  cxx: cl

We may need a more specific way to identify a distribution and maybe build once for 20.04 and once for 22.04. An alternative would be to only build for one and let the other compile from source every time.

We are using this file name as distribution identifier:

const WORKER_PREBUILD_TAR = `mediasoup-worker-${PKG.version}-${os.platform()}-${os.arch()}.tgz`;

Proposal:

• When in Linux (and only in Linux) we may also add the kernel major version (5, 6, etc) into that string.

We probably don't want "Linux" either, there are many distros with different versions of libraries. IIRC we are testing that the binary runs, but it doesn't guarantee it will not fail in runtime.

[ibc]

I don't understand, we need to know if it linux. Yes, it's indeed a limitation but we re not ready to create neither super universal binaries nor binaries for archs that we cannot run in CI.

Well, theoretically you can run VMs in CI, so strictly speaking it is possible to run any OS, whether it is worth it or not is a separate question of course.

Yes, but that's a separate story and super hard to accomplish.

I'm printing this in different archs:

console.log('platform-arch-release:', `${os.platform()}-${os.arch()}-${os.release()}`);

Debian GNU/Linux 12: platform-arch-release: linux-x64-6.1.0-13-amd64

Alpine Linux (running in Docker in macOS Intel): platform-arch-release: linux-x64-5.10.76-linuxkit

macOS Intel 13.6.1 (22G313): platform-arch-release: darwin-x64-22.6.0

Oh hell, Ubuntu 22.05 also comes with Kernel 5.15...

[nazar-pc]

22.05 is not a thing, but also for LTS versions there is newer HWE kernel, but it is not necessarily installed.
