net: zperf: Add support for bind to host option for tcp/udp download

Browse source 
The current zperf tcp/udp download command doesn't provide the option
to bind the server to a specific host address. If there is more than
one interface, it will not be possible to test each interface with zperf
tcp/udp download command without building the Zpehyr.

This patch will add support for zperf tcp/udp download command to bind
server to host interface address.
