packet: put all solutions to a separate directory

Sometimes it doesn't make sense to keep solutions from previous lessons in the
next. However, we want to have all solutions published. Create a new directory,
packet-solutions, which will store all the solutions from packet-* lessons.

Move existing solutions from the packet03-redirecting directory to the new one.
