Peter Hoyes df01b29f3f CI: Make update-repos more resilient to network issues
The update-repos script currently exits immediately if one of the
underlying Git commands fails (e.g. because of a network issue). If the
repo already exists, then catch this error inside the loop and
carrying on attempting to update other repos, as the network error may
be upstream.

KAS_REPO_REF_DIR is ultimately an optimization and subsequent build
stages should be able to continue if one of the updates fail. Therefore,
ensure the script returns a special error code if at least of the Git
commands fail, and use this to set the allow_failure property of the
job.

If a repo does not exist, fail immediately as before.
