update: re-enable updating local packages

PR #11584 removed the possibility of updating local
packages (linked with symlinks) with `npm update`.
Reason was that this functionality didn't work in
v3.6.0. However, the system behind local dependencies
has since changed, and I can't reproduce the original
error anymore.
