move stage0.txt to toplevel directory

[Keruspe]

This way all files needed by packagers now reside in toplevel

Is there a particular advantage to doing this? I wasn't aware that packagers cared too much about this -- I personally prefer to have as few top-level files as possible.

Eh I don't feel too strongly either way about this, so seems fine to me!

This failed x86_64-gnu-distcheck in #56376 (comment), because the new stage0.txt is not in the source tarball.

[Keruspe]

@Mark-Simulacrum It's mainly to make things "easier" for packagers. We use this for bootstrapping.

@kennytm should be fixed new

Caused the rollup to fail:

Well, it should have been a trivial change and it already made two rollups fail.

Definitely not worth it to keep trying, sorry about that guys!
