populate_sdk_base: avoid executing empty function

`bitbake uninative-tarball' raises the following warning.

    WARNING: Function  doesn't exist

This is because SDK_PACKAGING_FUNC is set to "" in its recipe.
Anyway, we need to check this variable to avoid executing empty function.

[YOCTO #7598]
