Documentation: bareudp: update iproute2 sample commands

Browse Source 
bareudp.rst was written before iproute2 gained support for this new
type of tunnel. Therefore, the sample command lines didn't match the
final iproute2 implementation.

There are two ways to create a bareudp device for MPLS & IP with multiproto mode The multiproto mode allows bareudp tunnels to handle several protocols of the
enabled. same family. It is currently only available for IP and MPLS. This mode has to
be enabled explicitly with the "multiproto" flag.

b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls_uc multiproto
For MPLS, the multiproto mode allows the tunnel to handle both unicast
and multicast MPLS packets.
