This is a revert of ae6e8ef1, but with a bit of refactoring,
and also specifically adding arm/aarch64, rather than all
architectures. Currently, libseccomp code appears to also support
mips, ppc, and s390. We could therefore allow qemu to enable
seccomp for those platforms as well, with additional configure
patches, given they're tested and proven to work.
