buildhistory.bbclass: create proper dependency files for SDK
The old functions were calling the list_installed_packages() wrapper
function that only listed the packages in an image rootfs. Even for
target/host SDK. Also, a python crash was possible if 'bitbake -c
populate_sdk core-image-*' was called without calling 'bitbake
core-image-*' first. That's because the wrapper was always looking into
the image rootfs...
This commit fixes the problem and calls the right wrapper for image/sdk.
