identify: only query remote bookmarks if needed

Instead of all the time when operating on a remote repo. This
perf regression was introduced in 15a79ac823e8, in 4.3.

This datahint method returns nothing for -Tjson, -Tpickle, -Tdebug
--config ui.formatdebug=true and --config ui.formatjson, so the
bookmarks won't show up. I don't know what these formatters are for.
plainformatter and templateformatter work properly, and the few other
uses of datahint should have the same kind of problem.

There is further weirdness where "--template '{node}'" is not enough
to avoid querying the bookmarks, you also need to pass --id or -q.
