1. rpm: disable seccomp to prevent tar EPERM (Fedora 40 ppc64le on Debian) …

   commit 07b5d90 disabled seccomp for the
   deb-builds because `chmod` failed tar was failing with an EPERM (Ubuntu
   24.04 armhf on 20.04 host).
   
   It looks like the same problem happens when running Fedora 40 on a Debian
   bookworm host on ppc64le.
   
   That issue was confirmed to be related to `fchmodat2(2)`, which is a new
   syscall that's not supported on the host, and therefore gets the seccomp's
   default EPERM;
   
       fchmodat2(AT_FDCWD, "docker", 0775, AT_SYMLINK_NOFOLLOW) = -1 EPERM (Operation not permitted)
       tar: docker: Cannot change mode to rwxrwxr-x: Operation not permitted
       tar: Exiting with failure status due to previous errors
   
   Ultimately we need to update the libseccomp profile to use ENOSYS (see
   moby ticket 42871) to allow it to degrade gracefully;
   
       fchmodat2(AT_FDCWD, "docker", 0775, AT_SYMLINK_NOFOLLOW) = -1 ENOSYS (Function not implemented)
