Find.find -> Use Dir.children instead of Dir.entries

Dir.children is available since Feature #11302.
Find.find can use of the new list (having no '.' neither '..' entries),
making now superflous an if statement.

This change can improve the performance of Find.find when the path
has lots of entries (thousands?).
