Add support for NetBSD DLT_PPP_SERIAL (PPP in HDLC-like framing, as per

RFC 1662, or Cisco point-to-point with HDLC framing, as per seciont
4.3.1 of RFC 1547; there's always an address and control octet at the
beginning of these packets, but they're not necessarily 0xff 0x03),
which we map to PCAP_ENCAP_PPP_HDLC.
