Revert "Add missing RDEPENDS of initscripts-functions"

Instead of manually adding initscripts to RDEPENDS of each package,
we should make it automatically handled by the update-rc.d.bbclass.
This solution would have the benefit of backward compatibility. In
other words, users need not modify their recipes.

This reverts commit 16080a3485bd793edd66ed8361f1e8b86a9e19ea.
