Avoid rbind /sys for chroot snap pre-seeding (cgroups fail to unmount)
Builds in LP with the Xenial kernel were happy with the recursive mount of
/sys inside the chroot while performing snap-preseeding but autopkgtests
with the groovy kernel failed.  With the groovy kernel the build was
unable to unmount sys/kernel/slab/*/cgroup/* (Operation not permitted).

This patch mounts /sys and /sys/kernel/security in the chroot in the
same way we've added for binary hooks.  This provides the paths under
/sys needed for snap-preseed while avoiding issues unmounting other
paths.
