testing/frr: new aport for free range routing, a fork of quagga

FRRouting is free software that implements and manages various
IPv4 and IPv6 routing protocols.

Currently FRRouting supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2,
RIPng, IS-IS, PIM-SM/MSDP, LDP and Babel as well as very early support
for EIGRP and NHRP.

During PR review, fix for openrc-run issue discovered and fix contributed
by Hidde Van der Heide.

+    tests/isisd: bypass test_fuzz_isis_tlv when inet_ntop is broken
+    
+    On Alpine Linux edge, musl does not seem to be RFC 5952 4.2.2
+    compliant (how to print a single :0: in the IPv6 address).  Let's
+    skip that test, as we get false negatives when running against
+    that version of musl.
+    
+    Credit for the idea for the fix and how to fix it is due to
+    chris@opensourcerouting.org.
+    
+    Testing done:
+    
+    make check on alpine linux passes now
