[PATCH] deb-src: do not error but warn for missing source packages

["'Cedric Hombourger' via isar-users" <isar-users@googlegroups.com>]

Some package repositories may only provide binary packages and no
source packages. While this is unfortunate, it shouldn't be fatal
either. Collect names and versions and print a warning for each.
