mkList: Scrub better
Clearing v.app.right was not enough, because the length field of a list only takes 32 bits, so the most significant 32 bits of v.app.left (a.k.a. v.thunk.env) would remain. This could cause Boehm GC to interpret it as a valid pointer. This change reduces maximum RSS for evaluating the ‘tested’ job in nixos/release-small.nix from 1.33 GiB to 0.80 GiB, and runtime by about 8%.
