[Virtio-fs] [virtiofsd-rs] MR merged: Fix support for non-x86 architectures

[virtiofs-bot at sinrega.org]

Fix support for non-x86 architectures, or at least for aarch64 and s390x. In addition for some minor adjustments to the seccomp filter, we need to bring a newer version of `capng` that fixes building on non-x86, and patch `virtio-queue` to a fork that supports big-endian arches.

The `virtio-queue` API is currently in a turmoil, so I'm marking this one as a draft until we know what's going to happen upstream. I don't discard having to keep using a fork for a while.
