oeqa/manual/sdk.json: Updated toolchain tarball to core-image-sato

Manual test step for SDK is updated. Previously toolchain was "poky-glibc-x86_64-core-image-sato-sdk<type-arch>-toolchain-<release-version>.sh"
But toochain for core-image-sato-sdk is not available in releases after 2.1, hence changed it to "poky-glibc-x86_64-core-image-sato-<type-arch>-toolchain-<release-version>.sh

Other less significant update is to add exepcted result in intermediate test steps.
