Yum calls open file callback twice for some packages which
makes our callback try second download and fail in some
cases. See the bz for details.

Resolves: rhbz#506361

Though this seems to be a yum bug, there is no will to fix it
there (it doesn't cause errors on installed system) so here
I am sending a patch on anaconda side.
