Bug#807611: kfreebsd-kernel-headers: vm/vm.h not usable

[Sergey B Kirpichev <skirpichev@gmail.com>]

Package: kfreebsd-kernel-headers

When trying to build monit package
https://packages.qa.debian.org/m/monit.html
it seems one can't include boolean_t from vm/vm.h, see e.g.
https://buildd.debian.org/status/fetch.php?pkg=monit&arch=kfreebsd-amd64&ver=1%3A5.15-2&stamp=1449372521

The reason was vm/vm.h (or any it's prerequisite) don't
have vm_ooffset_t definition.

Source to reproduce the failure (from config.log):
