selftests: set sysctl bc_forwarding properly in router_broadcast.sh
sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2, otherwise the bc packets from $rp2 won't be forwarded. This patch is to add this setting for $rp2. Also, as ping_test_from does grep "$from" only, which could match some unexpected output, some test case doesn't really work, like: # ping_test_from $h2 198.51.200.255 198.51.200.2 PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data. 64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms When doing grep $form (198.51.200.2), the output could still match. So change to grep "bytes from $from" instead.
