Make sure repoclosure cache cleaned when running as root

When running repoclosure as root user, it will use other dir instead of
the one returned by getCacheDir().

For yum, with --tempcache option could let the cache dir returned by
getCacheDir() always be used.

For dnf, there's no such an option and we have to handle it specially.
