nixos/boot: add /var/lib/nixos to pathsNeededForBoot

Browse source 
/var/lib/nixos is used by update-users-groups.pl in the activation
script for storing uid/gid mappings. If this has its own mountpoint
(as is the case in some setups with fine-grained bind mounts pointing
into persistent storage), the mappings are written to /var/lib, /var,
or /. These may be backed by a tmpfs or (otherwise ephemeral storage),
resulting in the mappings not persisting between reboots.
