Indeed it has change!  I've reported it upstream here:
https://github.com/opencontainers/runc/issues/2895.  To learn about what
changed, I ran the following commands:

--8<---------------cut here---------------start------------->8---
$ wget https://ci.guix.gnu.org/file/runc-1.0.0-rc6.tar.xz/sha256/1c7832dq70slkjh8qp2civ1wxhhdd2hrx84pq7db1mmqc9fdr3cc -O old.tar.xz

$ wget https://github.com/opencontainers/runc/releases/download/v1.0.0-rc6/runc.tar.xz -O new.tar.xz

$ diffoscope old.tar.xz new.tar.xz
--8<---------------cut here---------------end--------------->8---

And found that a slash went missing (weird):

Note that I recently updated the package to v1.0.0-rc93.

Thanks for the report!

Closing.
