Use pungi_buildinstall without NFS

Browse Source 
The plugin supports two modes of operation:
1. Mount a shared storage volume into the runroot and have the output
   written there.
2. Have the plugin create a tar.gz with the outputs and upload them to
   the hub, from where they can be downloaded.

This patch switches from option 1 to option 2.

This requires all input repositories to be passes in as URLs and not
paths. Once the task finishes, Pungi will download the output archives
and unpack them into the expected locations.
