Update libpatricia license

MRT was finally put on GitHub and its license changed to a
2-clause-BSD[1]. This license change was also propagated to Perl's
Net::Patricia[2], from which rPatricia borrows. We import the new
license from Net::Particia and place it (together with credits.txt)
under ext/rpatricia.

+   
+   MRT was developed by [1]Merit Network, Inc., under National Science
+   Foundation grant NCR-9318902, "Experimentation with Routing Technology
+   to be Used for Inter-Domain Routing in the Internet."

+   The BGP4+ extension was originally written by Francis Dupont
+   <Francis.Dupont@inria.fr>.
+   
+   The public domain Struct C-library of linked list, hash table and
+   memory allocation routines was developed by Jonathan Dekock
+   <dekock@cadence.com>.
+   
+   Susan Rebecca Harris <srh@merit.edu> provided help with the
+   documentation.
+   David Ward <dward@netstar.com> provided bug fixes and helpful
+   suggestions.
+   Some sections of code and architecture ideas were taken from the GateD
+   routing daemon.
+   
+   The first port to Linux with IPv6 was done by Pedro Roque
+   <roque@di.fc.ul.pt>. Some interface routines to the Linux kernel were
+   originally written by him.
+   
+   Alexey Kuznetsov made enhancements to 1.4.3a and fixed the Linux
+   kernel intarface. Linux's netlink interface was written, referring to
+   his code "iproute2".
+   
+   We would also like to thank our other colleagues in Japan, Portugal,
+   the Netherlands, the UK, and the US for their many contributions to
+   the MRT development effort.
