This is caused by a Nix upgrade on the build farm machines. Builds now run in a
user namespace, which confuses some of them. I've applied aszlig's seccomp patch
(https://github.com/NixOS/nix/pull/1131) which fixes some problems (like the go
build).

This one seems to be confused by setuid/setgid not working as expected, which is
hard to avoid in a user namespace with only one uid...
