[PATCH] NEWS: a few formatting updates for 0.21 news items (wiki compatibility)

[Tomi Ollila]

Trailing dots were removed from 3 NEWS items so that those appear in
same level as surrounding "heading" lines in generated wiki page.

One trailing dot was added to nmbug-status item so it appears as normal
text in generated wiki page. `nmbug-status` was put in backticks so it
looks the same as in older nmbug-status news text.
