Currently, installed packages are listed for images in image-info.txt, but
not for SDKs in sdk-info.txt. Add TOOLCHAIN_HOST_TASK and
TOOLCHAIN_TARGET_TASK to the output variables in sdk-info.txt.
Moreover, package output files for the SDK host are empty because
PKGDATA_DIR defaults to the target directory. Fix this bug and create a new
variable called PKGDATA_DIR_SDK which stores the correct path for the SDK
host package data.
