[nautilus] query: change raking to always sort closest files first

commit 27d3f2ba5543f18fb2accf9c7ef3bd9bf55795a5

    query: change raking to always sort closest files first
    
    And among those with the same distance from the search root, add more
    bonus for recency and FTS rank. This ensures results don't move too much
    when searching recursively.
    
    Also, while we're at it, change the code to use GFile instead of simple
    string comparisons.
