trafgen: fix packet socket initialization with multiple CPUs
The commit 78c13b71e196 ("trafgen: Allow to generate packets
to output pcap file") introduced a regression when output is
a network device and multiple CPU are in use: the packet
socket is created before fork() and thus the socket is shared
among all the processes: all of them except the first will
fail while setting the tx_ring.
Fix it splitting the io open() helper in a create() op,
called before forking, and the open() op called by each process.
