selftests: net: Add VXLAN MDB test

Add test cases for VXLAN MDB, testing the control and data paths. Two
different sets of namespaces (i.e., ns{1,2}_v4 and ns{1,2}_v6) are used
in order to test VXLAN MDB with both IPv4 and IPv6 underlays,
respectively.

Example truncated output:

 # ./test_vxlan_mdb.sh
 [...]
 Tests passed: 620
 Tests failed:   0

+# This test is for checking VXLAN MDB functionality. The topology consists of
+# two sets of namespaces: One for the testing of IPv4 underlay and another for
+# IPv6. In both cases, both IPv4 and IPv6 overlay traffic are tested.
+#
+# Data path functionality is tested by sending traffic from one of the upper
+# namespaces and checking using ingress tc filters that the expected traffic
+# was received by one of the lower namespaces.
