Upgrade OpenVSwitch to version 2.5.0 to support kernels up to 4.3

Most patches for 4.1 are no longer needed, only a minor patch to fix a
missing WAIT_ANY constant. 2.5.0 depends on nf_conntrack (ipv4 and ipv6)

-`csum_ipv6_magic` is an asm inline on most platforms. However if it is
-not defined (like on ppc64le) including <net/ip6_checksum.h> will fall
-back to the c implementation by wrapping it in an
