[OE-core] [PATCH 03/10] classes/populate_sdk_ext: handle lack of uninative when filtering sstate

[Paul Eggleton]

If the build in which the eSDK is being built isn't using uninative,
this will have an effect on NATIVELSBSTRING, which will mean that the
eSDK installer won't be able to find any of the native sstate packages.
To keep things simple, under this scenario just disable uninative
temporarily while we run the SDK installer to help us check the presence
of the sstate artifacts we need. Ideally I'd rather not have things like
this that are artificial in this verification step, but on the other
hand this was the least ugly way to solve the problem.
