Use kqueue as the backend of AE on DragonFlyBSD (#450)

Browse Source 
Currently, we use select(2) on DragonFlyBSD while
`kqueue` is available on DragonFlyBSD since FreeBSD 4.1
and DragonFlyBSD was originally forked from FreeBSD 4.8

`select(2)` is a pretty old technique that has many defects
compared to `kqueue`, we should switch to `kqueue` on DragonFlyBSD.
