[ubsan] Don't add a --dynamic-list for ubsan symbols when building a shared
library. That results in the linker resolving all references to weak symbols in
the DSO to the definition from within that DSO. Ironically, this rarely causes
observable problems, except that it causes ubsan's own dynamic type check to
spuriously fail (because we fail to properly merge type_info object names).
