[GIT PULL] seccomp updates for v4.16-rc3

[Kees Cook <keescook@chromium.org>]

Hi James,

Please pull these seccomp changes for v4.16-rc3. These are fixes for the
get_metadata interface that landed during -rc1. While the new selftest
is strictly not a bug fix, I think it's in the same spirit of avoiding
bugs.

Thanks!
