Add strong relation between initscripts and initscripts-service.
Also update Obsoletes of initscripts package.

Obsoletes with initscripts < 10.10 in order to allow the initscripts-service package to be installed while upgrading from initscripts < 10.10

The network-scripts package is legacy and deprecated, so nobody should depend on this!
If ifcfg-style configuration is still desired, NetworkManager can do this.
Thus, mark this as deprecated to ensure people know to not depend on it.

As a easy way to get full legacy system V support.

This changes moves service script into initscripts-service subpackage.
The subpackage could be install without main package.

This change allows audit not to require initscripts and require only
initscripts-service instead.
