[Virtio-fs] [virtiofsd] MR merged: seccomp: Allow `SYS_sigreturn` for s390x

[virtiofs-bot at sinrega.org]

The virtiofsd currently crashes on s390x. This is because of a `sigreturn` system call.

This was originally reported and fixed, for the C version, by Marc Hartmayer <mhartmay at linux.ibm.com>
