commit 188759bb documented the intent
to allow recursive dlopen based on tracking ctor_visitor, but used a
kernel tid rather than the pthread_t to identify the caller. as a
result, it would not behave as intended under fork by a ctor, where
the child tid would not match.

Use atexit to register some callback from dso, but there is no
unregister interface. After this dso closed, this callback in
atexit callback chain is invalidate. This workround will save
the dso that the callback come from, then when dso closed, the
relative callbacks would cleared.

Issue： #I6UEZQ
Test：register atexit cb, then dlclose this dso
