[bug#30603] Upgrade Racket to 6.12

[Christopher Lemmer Webber]

Okay... I worked upstream, and here's the upstream patch.  If accepted
this also closes out bug#30714.

I've done this as two separate patches (one with my original patch and
then one with the suggested update from upstream) because the patch
doesn't apply automatically pre- 6.12 anyway, so it makes sense to patch
with the minimalist patch, and then with the full fix.
