[PATCH 05/19] tree_entry_interesting(): remove dependency on struct diff_options

This function can be potentially used in more places than just tree-diff.c. "struct diff_options" does not make much sense outside diff_tree_sha1().

While removing the use of diff_options, it also removes tree_entry_extract() call, which means S_ISDIR() uses the entry->mode directly, without being filtered by canon_mode() (called internally inside tree_entry_extract)
