To use this option pass '--zerocopy' parameter:

./vsock_perf --zerocopy --sender <cid> ...

With this option MSG_ZEROCOPY flag will be passed to the 'send()' call.

Changelog:
v1 -> v2:
* Move 'SOL_VSOCK' and 'VSOCK_RECVERR' from 'util.c' to 'util.h'.
v2 -> v3:
* Use 'msg_zerocopy_common.h' for MSG_ZEROCOPY related things.
* Rename '--zc' option to '--zerocopy'.
* Add detail in help that zerocopy mode is for sender mode only.
