hex-packages: delete transitively unbuildable packages

[orivej]

Motivation for this change

Fixes #26279 as proposed in #31380 (comment) by dropping definitions of packages that depend on missing packages. This file is supposed to be autogenerated, but currently it can't be easily updated and it has not been updated since #16122.

After this nix-env -f "<nixpkgs>" -qaP -A beamPackages works.
