PACKAGERS: update Btrfs graphdriver dependencies

We only need suitable UAPI headers now. They are available on kernel 4.7
and newer; out of the distributions currently in support that users
might be interested in, only Enterprise Linux 7 has too old a kernel
(3.10).

Users of Enterprise Linux 7 distros can compile using a newer platform,
disable the Btrfs graphdriver as documented in this file, or use newer
kernel headers on their older distro.

* AUFS graph driver (requires AUFS patches/support enabled in the kernel, and at
least the "auplink" utility from aufs-tools)
* BTRFS graph driver (requires BTRFS support enabled in the kernel)
* BTRFS graph driver (requires suitable kernel headers: `linux/btrfs.h` and `linux/btrfs_tree.h`, present in 4.7+; and BTRFS support enabled in the kernel)
* ZFS graph driver (requires userspace zfs-utils and a corresponding kernel module)
* Libseccomp to allow running seccomp profiles with containers
