Do the same sort of checks whether ether_ntohost() is declared that we

do in libpcap for ether_hostton().  Include <netinet/ether.h> only if it
declares ether_ntohost().  If nothing declares it, declare it ourselves,
as we do in libpcap.

Don't cast the second argument to ether_ntohost() to a const pointer, as
some systems don't modify it but don't declare that argument as a const
pointer.  (This is similar to what we do on libpvap for
ether_hostton().)

Fix indentation.
