Fix: Binary sevctl was absent from debian packages

[hoh]

Solution: Build sevctl using an upstream version of Rust (the version in Debian is not supported), and bundle it in the Debian packages.

Add a setting in aleph-vm with the path of the bundled binary.

LGTM but shouldn't we do some kind of caching for this not not agravate the CI time further

If we enable git submodules on the repo, maybe we need to also add it on the docs.
