[PATCH 5/5] ce_path_match: drop prefix matching in favor of match_pathspec

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

ce_path_match() and tree_entry_interesting() are two functions that do
entry filtering when traversing trees. Now that
tree_entry_interesting() understands wildcard, ce_path_match() can
just use match_pathspec() to also understand wildcard.
