Lua: add routines to return pcap/nsec pcap/pcapng file type/subtypes. 

These will be backported, for the benefit of Lua scripts that want those
specific file types/subtypes (typically in order to write files of those
types); that allows those types to be fetched without having to know the
right string to hand to wslua_wtap_name_to_file_type_subtype().
