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.

If musl.dl.debug.dlclose is enabled, the sections of dlclosed library will not be unmapped.
Instead the mmap area will be set to PROT_NONE. If the program run into the dlclosed library
the crash log would contain the library info rather than a unmapped pc.
The param can be set by following cmdline:
param set musl.dl.debug.dlclose enable
