Enable UndefinedBehaviorSanitizer

The -fvisibility=hidden option disables a generation of the rtti information
for some classes with hidden visibility, this information is critically
needed for ubsan VPTR check. Since this library needed to ise-default package,
we should just disable visibility option with ubsan to avoid situation
with undefined reference to typeinfo.
