Add support for DragonFlyBSD to memsup
DragonFly was partially supported by os_mon already but when trying to start the os_mon application it'd crash with an error about an unknown operating system in memsup. This patch changes memsup to use the FreeBSD sysctl method to get memory information when on DragonFly.
