Remove calls to sudo if already root

[p5]

If you run rechunk as a root user already, rechunk tries to sudo again.
This can be problematic if you're running rechunk via a container image that doesn't have sudo installed.

can you print the full stacktrace?

Sure!

Run hhd-dev/rechunk@602e6d62558ab23e15e8764ce06e26c0f328da71
  with:
    rechunk: ghcr.io/hhd-dev/rechunk:v1.0.1

For now, I've aliased sudo to a no-op, but it would be good not to.

Not an urgent change though, since the alias works fine.

There are two problematic sudos in rechunk, i just removed them:
20a6e58

The container we ship has them so its a noop though.

As for the sudo you are running into, thats from the github action. Since you are running a github action, it is expected to run as a normal user with sudo as escalation

So unsure what to do about that. Also, running the action nested from a container image is something that will probably cause a lot of other issues.
