Fixed in commit bc459b6, which skips the tests if /proc/self/setgroups
does not exist, rather than allowing a system with a vulnerable kernel
create containers with a new user namespace.

I would like to note that you should update your kernel as soon as
possible, as the lack of /proc/self/setgroups means that you are
running a kernel with a known security vulnerability.  The fix was
introduced in Linux 3.19, but backported to many older kernels,
including 3.13.

Thanks,

- Dave
