Show "Not logged in" message

Show "Not logged in" message left or right (depending on language) of an anon
user's personal tools in case general edit permission is given.

The display of the message was previously done in MW core
(SkinTemplate::buildPersonalUrls, introduced by I6f44e3e5d), which needs to be
reverted first (done in I5cfa9b4e).
