ui-plain: more efficient walk_tree()
Git's read_tree_recursive() already filters out the objects by pathname, so we only have to compare baselen to the expected. That is, no string matching is required. Additionally, if the requested path is a directory, the old code would walk through all of its immediate children. This is not necessary, this so we no longer do that.
