net/if_dl.h: make self-contained

Browse Source 
include <sys/_types.h> for u_char and u_short.

to avoid including <sys/types.h>, remove the caddr_t cast from LLADDR.
we are trying to get rid of caddr_t anyway, and since sdl_data is
already an array of char, the cast is unnecessary.  this also makes
LLADDR const-correct, i.e. passing a const sockaddr_dl will return a
const pointer.
