Subject: [PATCH 1/2] Unpack the bundled Node tarball for the machine's
 architecture

An aarch64 ISO bundles node-v*-linux-arm64.tar.gz, and mise-work.sh
looked for node-v*-linux-x64.tar.gz on every machine. An offline install
on aarch64 stopped at its last step: "Error: bundled Node.js tarball
missing from /opt/packages".

The name now follows uname -m. x86_64 looks for the same file as before.
This is the change the n1x branch already carries, from Spencer Bull's
6d022e36.

Subject: [PATCH 2/2] Test that each architecture unpacks its own Node tarball

The existing test runs mise-work.sh in the runtime context, which skips
the bundled tarball altogether. This offers both tarballs to an x86_64
and an aarch64 machine and checks that each unpacks its own and hands
Mise that version, and that a machine with only the other architecture's
tarball fails. Against the old script the aarch64 case fails.
