drop script 'rotate-ntp'change-81

For RouterOS 6.x a separate package 'ntp' exists. This adds server
functionality, but allows ip addresses for the client only. I added the
script 'rotate-ntp' to update addresses from names...

Now with RouterOS 7.x there's no extra package and the limitation does
no longer exist. So let's just drop the script.

This adds migration code, that...
 * removes the script from configuration
 * removes a scheduler from configuration
 * sets the configured ntp pool name for ntp client
