We had centos stream and altarches and centos linux under /srv/pub on
external download servers. However, this breaks people who sync buffet
or the like from them because they suddenly get centos content that they
want to just get directly elsewhere. So, just move these up a leave so
they are out of the buffet target and people who want them can get them
elsewhere.
