  1. Use seccomp instead of setsid() to workaround CVE-2017-5226 

    The setsid() workaround of
containers#143 is problematic,
because it e.g. breaks shell job control for bubblewrap instances.
So, instead we use a seccomp approach based on:
 util-linux/util-linux@8e49250
However, since we don't want to pull in any more dependencies into
the setuid binary we pre-compile the seccomp code during the build.

If libseccomp is not available on your architecture, we still support
the old fix with --disable-seccomp-tty-fix.

This fixes containers#147
