[oe] [PATCH v2] classes/native*.bbclass: fix error during parse with bitbake master

[Paul Eggleton]

Fixes "AttributeError: 'NoneType' object has no attribute 'split'" during
parsing with bitbake master. We should not be calling explode_deps with
None as the argument, so ensure the value isn't None.
