chroot_version_hooks.d: drop support for upgrading SDKs pre-2015

Punt a lot of old upgrade hooks that only get used for SDKs that were
created before 2015 and have not been upgraded since.  The tooling will
already detect this scenario (because the upgrade hooks are missing) and
throw an error telling the user to recreate the SDK.  Chances are good
that it wouldn't actually work, and we certainly have no testing to make
sure that it does.  So punt it all.

TEST=precq passes
