selftests: vxlan_mdb: Fix failures with old libnet

[ Upstream commit f1425529c33def8b46faae4400dd9e2bbaf16a05 ]

Locally generated IP multicast packets (such as the ones used in the
test) do not perform routing and simply egress the bound device.

However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding:
Fix failing tests with old libnet"), old versions of libnet (used by
mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically,
the library started using the option for IPv6 sockets in version 1.1.6
and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which
uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6
ones are passing.

Fix by specifying the source and destination MAC of the packets which
will cause mausezahn to use a packet socket instead of an IP socket.
