Fail stuck ISO E2E runs sooner

A hung installer used to burn up to 60 minutes, and a stuck first boot
another 30, before failing. Cut the limits to a few times a healthy run
(install 30 min, first-boot test 15 min, core services 10 min) and the
job timeout from 180 to 90 minutes, which still covers the worst case
of every phase plus the retried ISO build.
