To enable DPDK it needs a positional parameter to ovs-vswitchd.
Since everybody is encouranged to use the project provided ovs-ctl
scripts to start/stop the daemons it should allow an external setting of
these options via an environment variable.
This patch adds $DPDK_OPTS which will be inserted in the call to
ovs-vswitchd arguments early.
