Since 6c30c9ac47 (samples: net: zperf:
Rewrite upload part to use sockets), zperf uses SO_RCVTIMEO in UDP mode,
hence must depend on/enable support for it.
Without SO_RCVTIMEO support, zperf fails like this:
> nb_packets=47 delay=188964 adjust=-13
> setsockopt error (109)
> setsockopt error (109)
> -
> Upload completed!
> LAST PACKET NOT RECEIVED!!!
> Statistics: server (client)
> Duration: 0 us (10.19 s)
> Num packets: 0 (50)
> Num packets out order: 0
> Num packets lost: 0
> Jitter: 0 us
> Rate: 0 Kbps (9 Kbps)
