fix support for go1.22rc1

In early December, a new internal package linknamed from runtime
was introduced, internal/chacha8rand. Re-generate the tables.

Note that due to the same group of CLs and refactors,
math/rand and net are no longer linknamed from runtime in Go 1.22.
They are still in Go 1.21, so keep those entries around for now.
We can remove math/rand/v2, as it doesn't yet exist in 1.21.

Fixes #820.
