Skip live network feed test under -short for deterministic make check (closes #2)

TestRouteWatchLiveFeed streams the live RIPE RIS feed for about five
seconds, which made make check nondeterministic and network-dependent.
Guard it with a testing.Short() skip and pass -short in both go test
lines of script/test, so the default suite runs offline and
deterministically. The README documents how to run the live test on
demand.

Test-only change; no production behavior changes.
