populate_sdk_base: Include do_rootfs depends for do_populate_sdk
"bitbake core-image-minimal -c populate_sdk; rm tmp -rf; bitbake core-image-minimal -c populate_sdk"
breaks due to missing dependencies on things like update-rc.d. Since
we're effecitvely building a rootfs, we need all the same depends
as do_rootfs has.
The easiest was to achieve this is to simply load them. This resolves
the failure when targeting the task from sstate.
