Tweak mark-base attachment Apparently a base glyph can also become an attached component of a ligature if the ligature-forming lookup used IgnoreBase. This was being confused with a non-first component of a MultipleSubst and hence not matched for mark-attachment. Tweak test to fix. Fixes https://github.com/behdad/harfbuzz/issues/543
