meta-tizen: Explicitly add dependencies for the target build

This prevents ail build from failing. It is not clear why explicit
dependencies to libslp-db-util and xdgmime are required for the target
build since those dependencies are already present in the recipe (for
both native and target builds).
This issue is similar to the one with vconf: BTY-14.
