[INET]: Collect common frag sysctl variables together
Some sysctl variables are used to tune the frag queues
management and it will be useful to work with them in
a common way in the future, so move them into one
structure, moreover they are the same for all the frag
management codes.
I don't place them in the existing inet_frags object,
introduced in the previous patch for two reasons:
1. to keep them in the __read_mostly section;
2. not to export the whole inet_frags objects outside.
