[OE-core] [PATCH 2/2] lib/oe/package_manager: avoid traceback with no packages

[Paul Eggleton]

If you were using deb packaging, had buildhistory enabled and produced
an SDK that contained no packages in one of the sysroots (such as with
uninative-tarball) then the do_populate_sdk was failing with a python
traceback because there were no fields to split in the output line.
