base-images: Use https for yum repo

[chlunde]

buildlogs.centos.org is now on https. yum failed to follow the
http to https redirect, so change the URL to https to avoid the redirect:

Just to comment on this : we always had redirect in place for more than one year (just for the CDN backend) and we enforced https already on Jan 30 2017 (just had a look at puppet/git)

[chlunde]

The problem with handling redirects in yum is only an issue when there's a TLS content inspection proxy in place.

Still, the site is now https so there's no point in having it use http in the config file.

@chlunde thanks for the contribution! Let's see this pass tests and merge. Would you mind doing PRs to the release-1.4 and release-1.5 branches with the same fix?
