runtime: fix sysctl calling convention on netbsd/386

Browse Source 
Thanks to coypoop for noticing at:

  https://github.com/golang/go/issues/22914#issuecomment-347761838

FreeBSD/386 and NetBSD/386 diverged between Go 1.4 and Go 1.5 when
Russ sent https://golang.org/cl/135830043 (git rev 25f6b02ab0)
to change the calling convention of the C compilers to match Go.
But netbsd wasn't updated.

Tested on a NetBSD/386 VM, since the builders aren't back up yet (due
to this bug)

Fixes #22914
Updates #19339
Updates #20852
Updates #16511
