feat(nix/runExecline): add runExecline r/1132

runExecline is a primitive that just does not care.

It’s similar to `runCommand`, but instead of concatenating bash
scripts left and right, it actually *uses* the features of
`derivation`, passing things to `args` and making it possible to
overwrite the `builder` in a sensible manner.

Additionally, it provides a way to pass a nix string to `stdin` of the
build script.

Similar to `writeExecline`, the passed script is not a string, but a
nested list of nix lists representing execline blocks. Escaping is
done by the implementation, the user can just use normal nix strings.
