[meta-freescale] [meta-fsl-arm][PATCH 1/2] image_types_fsl: Use explit task dependency to boost build

[Otavio Salvador]

Instead of depending of all tasks of recipes, we should depend on the
required task so we can start building the rootfs earlier in the build
process and earn some build time gain.
