rPackages.littler: fix build (#51282)

littler gives a wrapped called `r` (or `lr` for non-case-preserving
systems like Darwin) which works as shebang or pipe target.

The build was completely broken before (missing deps).

Symlink executables and manpage into standard locations so that this
packages also works in `environment.systemPackages`.
