<arpa/nameser.h>: Remove RR type classification macros [BZ #20592]

ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the
<arpa/nameser.h> header file because the distinction between RR types and
meta-RR types is not officially standardized, subject to revision, and
thus not suitable for encoding in a macro.
