`netboot-update` failed with an opaque curl usage error whenever the
`installer` tag advanced past a build that had not published assets:
the `jq` select found no matching asset, and the empty result was
passed straight to `curl` as the URL. Report the missing asset (and
an unresolvable tag) instead.
The unit also had its network dependency inverted, being `wantedBy`
network-online.target rather than wanting and ordering after it. Fix
the idiom and keep it in the boot transaction via multi-user.target.
On river that is not enough on its own, because the WAN is a pppd
interface that networkd's wait-online knows nothing about, so
network-online.target is reached well before there is a route
off-site. Gate the service on wan-online.target there, following the
same wantedBy + partOf idiom as ipsec, which also re-runs the fetch
whenever the link returns.
