feat(nix/binify): add binify r/1097
Create a store path where the executable `exe` is linked to
$out/bin/${name}. This is useful for e.g. including it as a “package”
in `buildInputs` of a shell.nix.

For example, if I have the exeutable /nix/store/…-hello, I can make it
into /nix/store/…-binify-hello/bin/hello with
`binify { exe = …; name = "hello" }`.
