[Tarantool-patches] [PATCH 0/2] Use GitHub-hosted runners for Linux/ARM64 jobs

[Alexander Turenko via Tarantool-patches]

The idea is simple: reduce effort to support of our own runners. I wrote
it in more details in https://github.com/tarantool/tarantool/pull/13278.
Here I propose the same change for tarantool/luajit.

As far as I can see, the changes should apply cleanly to the release
branches.

Technically the commits are written by an LLM, but I looked over it
carefully (mostly during work on tarantool's series, and this one
repeats the same changes).

Branch: Totktonada/arm64-jobs-on-github-hosted-runners
CI: https://github.com/tarantool/luajit/tree/Totktonada/arm64-jobs-on-github-hosted-runners

[Tarantool-patches] [PATCH 1/2] ci: use sudo to install packages if not root

[Alexander Turenko via Tarantool-patches]

The setup-linux and setup-debuggers actions call `apt` without `sudo`,
which works on our self-hosted runners: the jobs run there as root. The
next commit moves the ARM64 jobs to GitHub-hosted runners, where the
steps run as the runner's regular user, so we have to call `sudo` there.

If the current user is already `root`, `sudo` is not called: this way we
don't depend on its presence when we don't need it.

Drafted by an LLM, conducted and corrected by the commit author.

[Tarantool-patches] [PATCH 2/2] ci: run ARM64 jobs on GitHub-hosted runners

[Alexander Turenko via Tarantool-patches]

The main idea behind the switch is to have less of our own
infrastructure to support, see tarantool/tarantool#13278 for details.
