view: remove "threadlink" from thread view

We're already inside the thread, and our thread summary inside
/m/$MESSAGE_ID/ is already sufficient got navigate back to the
/t/$MESSAGE_ID/ page.  So I think it's sufficient to keep the
/t/$MESSAGE_ID/ page lighter with fewer links and avoid
introducing strange terminology.

In contrast, "permalink" is relatively well-known and
not an alien term to readers:
