install: restrict to nix-shell

Browse source 
This commit adds a "build" command to the install derivation that
tells the user that `nix-shell` should be used.

A derivation attribute `shellHookOnly = true` is also added with the
intent to indicate that the shell hook is the entire point of the
derivation.

(cherry picked from commit fcdab6a62d)
