Fix the problem with the nsupdate(8) man page reported

in the PR by removing spurious .HP tags, thereby actually
allowing the commands to show up in the man page output,
and making the style consistent with the nslookup(1) man
page. [1]

While I'm here, fix the markup on the first command reference
in nslookup(1).
