linkers: Make id a class variable for DynamicLinkers
Originally I had this idea that you'd be able to pass the id in to be
able to deduplicate some cases (like ld.gold and ld.bfd). That went away
because it ended up being really un-dry, but this id per instance
remained. Getting rid of it allows us to get rid of a bunch of otherwise
useless super calls, which makes adding type annotations easier.
