nix3-build: show all FOD errors with `--keep-going` Basically I'd expect the same behavior as with `nix-build`, i.e. with `--keep-going` the hash-mismatch error of each failing fixed-output derivation is shown. The approach is derived from `Store::buildPaths` (`entry-point.cc`): instead of throwing the first build-result, check if there are any build errors and if so, display all of them and throw after that. Unfortunately, the BuildResult struct doesn't have an `ErrorInfo` (there's a FIXME for that at least), so I have to construct my own here. This is a rather cheap bugfix and I decided against touching too many parts of libstore for that (also I don't know if that's in line with the ongoing refactoring work).

`nix build --keep-going` now behaves consistently with `nix-build --keep-going`. This means
that if e.g. multiple FODs fail to build, all hash mismatches are displayed.
