    mirror/centos: improve handling of the conflicting packages

    current version of mirror/centos/ has a couple of serious bugs:

    - error handling is flaky and incomplete, that is, the exit status of
      yumdownloader is ignored (due to misuse of shell pipeline). Instead
      the errors are detected by parsing the yumdownloader log which is
      unreliable (and adds a lot of extra code for no gain at all).

    - Inconsistent dependencies/conflicts are handled in an extremely flaky
      manner: the error code of yumdownloader is ignored, instead the total
      number of conflicts (or rather the number of "conflicts with" strings in
      the yumdownloader log) is compared with some magic number. No attempts
      are made to check which packages were conflicting, also the magic number
      should be adjusted whenever a new package is added into the repository

    - Current code uses the default RPM database and thus is unusable on RPM
      based systems.

    To solve these problems

    - process packages one by one, ask yumdownloader to print the URLs
    - use a separate RPM database to not interfere with the system one
    - use the error code returned by yumdownloader to check for errors
    - download the actual packages with wget
    - make sure the independent tasks can run in parallel

    As a side effect yum bug
    no longer affects building the ISO
