librpc: Do not access name[-1] trying to push "" into a dnsp_name
This simply matches the behaviour from before e7b1acaddf2ccc7de0301cc67f72187ab450e7b5
when the logic for a trailing . was added. This matches what is added in
the dnsRecord attribute for a name of "." over the dnsserver RPC
management interface and is based on what Windows does for that name
in (eg) an MX record.
No a security bug because we use talloc and so name will be just the
end of the talloc header.
