[layerindex-web][PATCH 2/3] update_layer.py: use DISTRO_NAME as primary distro short description

[Paul Eggleton <paul.eggleton@linux.intel.com>]

When reading conf/distro/*.conf to create distro records, attempt to
parse the config file and use DISTRO_NAME (if set) to populate the
description field for the record. If that's not set then fall back to
the less commonly used meta-comment that we supported previously.
