Prevent symlink creation in npm install

Vagrant on Windows has issues with creating symlinks inside shared
folders - it requires a permission that isn't granted to a user by
default. This can be fixed by changing security policies, but for our
purposes we don't need the symlinks anyway, and can run the tools
manually like this, instead of using the .bin/ symlinks.
