This further patch implements several syscalls used by firefox on debian-kfreebsd-amd64 which were not yet implemented (or for some reason had an implementation that was commented out)

Description: Implement several new syscalls for freebsd This fixes several unimplemented syscall messages seen when running firefox under valgrind. It is cumulative with my initial patch and probably should be squashed in. .
