Tor download link links to TBB download page

Some pages link to download TBB instead of Tor

• tor-doc-unix > https://www.torproject.org/download/download.html.en
• torproject.org > https://www.torproject.org/download/download-easy.html.en
• maybe others

Instead they should link to https://www.torproject.org/download/download-unix.html.en
