Context

The (experimental) (lint-opam) step sometimes fails with e.g.:

/src: (run (cache (opam-archives (target /home/opam/.opam/download-cache)))
           (network host)
           (shell "opam update --depexts && opam install --cli=2.2 --depext-only -y deps_for_opam_dune_lint.opam $DEPS"))
+ /usr/bin/sudo "apt-get" "update"

[ERROR] No package named deps_for_opam_dune_lint found.

Step(s) to reproduce

eio-trace always seems to get this error (see https://ocaml.ci.dev/github/ocaml-multicore/eio-trace). eio itself doesn't.

Expected behaviour

deps_for_opam_dune_lint appears to be a fake package only used during analysis. So presumably it should not appear in builds.
