Revert "buildNodePackage: enable strictDeps"

This reverts commit e0705250d2, which
broke patching `#!/usr/bin/env node` shebangs.

It also modified a generated file, which would get reverted the next
time node-env.nix is regenerated.

If we want to enable strictDeps for node packages we should update
node2nix instead.
