ntp: only rdepend on sysvinit files when needed

The sysvinit files were already split into its own package, but ntpd
unconditionally rdepended on it. Change that so that ntpd only pulls in
the sysvinit files if the global sysvinit flag is set by the distro.

While at it, give the package a less generic name.
