CI: use install-pmbootstrap.sh from ci-common repo (MR 1147)

This script is used by multiple repositories by now, let's make sure we
only have one place where we need to maintain it. The version in
ci-common is shellchecked and displays less output for 'pmbootstrap
init' again (unless it fails, then it shows the whole log).
