Get bsd-user host page protection code working on FreeBSD hosts
Use kinfo_getvmmap(3) on FeeBSD >= 7.x and /compat/linux/proc on older FreeBSD. (kinfo_getvmmap is preferred since /compat/linux/proc is usually only mounted on hosts also using the Linuxolator.) This patch is a bit hacky because the includes needed for kinfo_getvmmap conflict with other definitions in exec.c by default so I had to `trick around' a little, but I built the result in FreeBSD 6.4-stable and 7.2-stable tbs and on 8-stable on the host so the hacks at least should be stable. (If this is a problem maybe we could also move the kinfo_getvmmap invocations into a seperate source file but that would be more work...)
