[OE-core] [PATCH 1/1] base.bbclass: Work even when there's no PNBLACKLIST entries

[Peter Seebach]

It turns out that the result of getVarFlags is not a list, it's
a dict. So "getVarFlags(...) or []" does not reliably produce
something with a .items. This escaped detection because our
local build environment never ends up running builds without
PNBLACKLIST entries.
