postbuild.groovy: Instead of SQUAD links, match LAVA ones instead

SQUAD link doesn't do anything except redirecting to LAVA - as long as
a user following it has SQUAD access, otherwise it just 403s. Overall,
that only adds a layer of confusion here. Let's use both LAVA job IDs,
and LAVA job links right away.
