fixdep: use existing helper to check modular CONFIG options
str_ends_with() tests if the given token ends with a particular string. Currently, it is used to check file paths without $(srctree). Actually, we have one more place where this helper is useful. Use it to check if CONFIG option ends with _MODULE. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
