>Description:

rpcinfo in netbsd-10 (and -current) fails when resolving a hostname with
e.g.:

rpcinfo: thehost: servname not supported for ai_socktype

Reason is that the hostname is resolved with getaddrinfo() looking for
service "rpcbind" which is no longer an alias in our services database.

Adding the alias "rpcbind" to the "sunrpc" entry (and refreshing sysdb)
helps.

>How-To-Repeat:
rpcinfo -p thehost
>Fix:
Restore the rpcbind alias or modify the code to reference the service under
the IANA registered name "sunrpc".
