Title: Make `Pkg.build` error message clearer.

An itch I've long wanted to scratch.

Old:

```
WARNING: Images and IJulia had build errors.

- packages with build errors remain installed in /home/beyer/.julia
- build a package and all its dependencies with `Pkg.build(pkg)`
- build a single package by running its `deps/build.jl` script
```
