Eelco Dolstra 7349f257da Only mount /sys in uid-range builds
Maybe this should be a separate system feature... /sys exposes a lot
of impure info about the host system.

Eelco Dolstra ba50c3efa3 Add "uid-range" and "systemd-cgroup" system features
"uid-range" provides 65536 UIDs to a build and runs the build as root
in its user namespace. "systemd-cgroup" allows the build to mount the
systemd cgroup controller (needed for running systemd-nspawn and NixOS
containers).

Also, add a configuration option "auto-allocate-uids" which is needed
to enable these features, and some experimental feature gates.

So to enable support for containers you need the following in
nix.conf:

  experimental-features = auto-allocate-uids systemd-cgroup
  auto-allocate-uids = true
  system-features = uid-range systemd-cgroup
