Projects like mix2nix and my own project, deps_nix, are collecting a
growing number of workarounds for packages that depend on the working
directory of a build to have the same name as the package.
See for example: da2ebc2c63
This change makes the pname of Hex packages equal the package name, so
that such workarounds aren't necessary.
