Remove baseurl download.fp.o
    
    We want to discourage people from using download.fedoraproject.org, so
    hopefully we get less people to use it for package downloads by not
    "advertising" it as an option in the repo files.
    It is vastly suboptimal to using metalink for all parties involved.
