Fix swapctl() argument count detection on OpenBSD.

on OpenBSD swapctl() takes three arguments, but is defined in unistd.h
and also needs sys/param.h.

http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/swapctl.2

we need to add those headers to both detections to make sure the test
on 'swapctl takes two arguments' correctly fails.
