integration: fix ovs/dpdk with DPDK >= 18.02

In DPDK >= 18.02 disable-hw-vlan testpmd command line was changed.
Parameter disable-hw-vlan is default and user has to explicitly enable it.
This patch fix testpmd command line parameters. Also in DPDK >= 18.05
igb_uio kernel module was moved to different directory. Compilation of
kernel module only is broken. This patch fix this. Now whole DPDK
project is build.
