package/cups: add proper init script

Cups service for systemv was erroneously installed in /etc/rcX.d and
therefore not working. Also, its init script installed in /etc/init.d
was definitely not a Buildroot-style init script.

This patch adds a Buildroot style init script instead of using the
example provided by the package.
