[CCID3]: More to see in dccp_probe

This adds a few more fields of interest to /proc/net/dccpprobe, the following output ensues:

1           2          3           4     5  6     7   8        9        10   11
sec.usec   src:sport   dst:dport   size  s  rtt   p   X_calc   X_recv   X    t_ipi

Also made the formatting consistent.
