eclass-overlay: add netperf user and group

netperf-2.7 ebuild (upgrade depends on this CL) requires netperf user and group.

TEST=cd /mnt/host/source/src/third_party/portage-stable/net-analyzer/netperf
     <cherry-pick from>
     # assumes test/dev image already deployed on $B1/$B2
     cros deploy $B1 net-analyzer/netperf
     cros deploy $B2 net-analyzer/netperf

     netserver -V and netperf -V on respective machines should report:
     Netperf version 2.7.0

     (beware of /usr/local/bin vs /usr/bin/)

     On $B1: "netserver" and "iptables -I INPUT 1 -j ACCEPT"
     On $B2:
         $NETPERF -H 192.168.xx.yy -t TCP_MAERTS -B "RX Mbps" -- -s 256K -S 256K
