sterni 94cbf73aa2 libcmd: add support for lowdown >= 3.0.0
lowdown 3.0.0 merged some flags into one to save on bits and did not add
any aliases for backward compatibility.

As with the changes for lowdown >= 1.4, we define a preprocessor flag to
gate the changes on and add a job to CI to ensure that lowdown < 3.0
keeps working (which is used by NixOS 25.11).

Unfortunately, we need to jump through some hoops to prevent nix and lix
from upstream Nixpkgs from being rebuilt due to a changed lowdown. Since
both implementation's packaging in Nixpkgs has their own package set /
fix point now, we can't simply inherit them from `prev` since they will
always be (re-)computed from the `final` fix point. As a consequence,
we need to expose our changed lowdown version at a non-default attribute
or break the builds of Nixpkgs derivations we test against.
