MFC r233554:

 Export the udp_cksum sysctl for upcoming SCTP work.  Rather than always,
 SCTP will only do IPv4 UDP checksum calculation as defined by the host
 policy.  When tunneling SCTP always calculates the inner checksum already
 so not doing the outer UDP can save cycles.

 While here virtualize the variable.
