[integration-cli] fix p/z HubPullSuite tests

This test tries to pull all the tags in the busybox repo and looks to see
if there were more than two images pulled. This was failing on
p/z due to the recent change to manifest lists, where one of the busybox
tags didn't have a p/z manifest in it's manifest list.

This error seems fine to me, so I changed the test to see if pull fails,
it fails with the "manifest not found" error.

Also switched from busybox -> alpine, because it has significantly less tags,
and the images are close in size.
