To avoid exceeding the inputs number limit of the flex scanner used,
when calling getnameinfo() in inet_service_type_print().
The new symbol_table was associated with inet_service_type, to enable
listing all pre-defined services using nft command line tool.
The listed services are all well-known and registered ports of my
local /etc/services file, from Ubuntu 16.04. Service numbers are
converted to respect network byte order.
Signed-off-by: Elise Lennion <elise.lennion@xxxxxxxxx>

v2: Used symbol_table to list the services and put them in another
file. Also used network byte order on service values to replace
nft_service_lookup with symbolic_constant_print.
