nixos/activation-script: ensure gcroots dir exists

Browse source 
If the Nix daemon has never been enabled (nix.enable has always been
set to false), the gcroots directory won't exist.  If the Nix daemon
is later enabled, the GC roots for booted-system and current-system
will be missing, and they might end up being garbage collected.  Since
it's cheap to add GC roots even if the daemon will never be enabled,
let's just always add them so we're okay in the case where the daemon
is enabled later.
