update-rc.d: automatically rdepend on initscripts-funtions 

Automatically add 'initscripts-functions' to packages when needed.

This extra dependency is added only when the package's init script
would be used at system start-up. In other words, in a systemd based
image, if the package has already got its service files, it will not
have this extra dependency.
