[RFC PATCH nixpkgs v2 6/9] rustPlatform: forward unpack hooks to cargo fetch

30 Sep 2022

Sometimes it's more ergonomic to set up the build environment in
hooks, to add to the default behaviour rather than replacing it.  It's
very surprising that the fetcher works fine with a custom unpackPhase,
but not with custom preUnpack or postUnpack.
