print-dev-env: Avoid using unbound shellHook variable
Some tools which consume the "nix print-dev-env" rc script (such as
"nix-direnv") are sensitive to the use of unbound variables. They use
"set -u".

The "nix print-dev-env" rc script initially unsets "shellHook", then
loads variables from the derivation, and then evaluates "shellHook".
However, most derivations don't have a "shellHook" attribute.

So users get the error "shellHook: unbound variable". This can be
demonstrated with the command:

    nix print-dev-env nixpkgs#hello | bash -u

This commit changes the rc script to provide an empty fallback value
for the "shellHook" variable.

Closes: #7951 #8253
