The test generates a BPF with libseccomp API then runs a BPF simulator.
The libseccomp commit 51c46f80c1edee863bbc4eb21b03decc44e69a45 ("all:
block negative syscall numbers from the filter") seems to indicate this
is fixing and testing problems on the filter (which I read as BPF
filter), so this is unlikely a kernel problem.

However, it might be uncovering a libseccomp bug on s390.

Title:
  ubuntu_seccomp pseudo-syscall fails on s390

Status in ubuntu-kernel-tests:
  New

Bug description:
  libseccomp upstream has changed the test code for 29-sim-
  pseudo_syscall.c, which has broken it for s390. Perhaps s390 has been
  broken since forever and the test change is just uncovering it. We
  need to investigate if the fix would be needed in the test, libseccomp
  or the kernel. This seems to affect at least 4.4 and 5.4 kernels, but
  may affect everything.
