vars: fix re-generate behavior for dependencies of shared vars (#5001)

fixes https://git.clan.lol/clan/clan-core/issues/3791

This fixes multiple issues we had when re-generating shared vars.

Problem 1: shared vars are re-generated for each individual machine instead of just once (see #3791)

Problem 2: When a shared var was re-generated for one machine, dependent vars on other machines did not get re-generated, leading to broken state
