netgdb(4): update list of required kernel options

Browse Source 
The man page claims that netgdb will be enabled automatically with the
presence of the DDB, GDB, and INET options. Based on the logic in
conf/files, this is not the case. Update the manpage to list all
of the options required to include netgdb.
