Subject: [PATCH 1/2] nixos/netbox: clear old static files on upgrade

This fixes an issue where upgrading NetBox didn't correctly clean old
files, and the interface wasn't correct / didn't show object relations.

Subject: [PATCH 2/2] nixos/netbox: switch to symlink to check for upgrades

This makes it so that the upgrade script also runs when the
configuration changed, or when plugins were added.

This is also a hack to force everyone to run the upgrade script again,
since static files might have been copied incorrectly (see parent commit)
