system/activation: mention deps attr in activationScripts example

Browse Source 
As it helps making deps easier to discover - as we don't currently
render submodule options in the module correctly - and is arguably
more technical correct: When using nixos-install to install nixos
into a chroot in i.e. /mnt, there's no gurantee that /mnt/dev exists
before the specialfs phase ran.
