They don't seem to do anything useful in lsan.
They are needed only if a tools needs to execute
some custom logic during detach/join, or if it uses
thread registry quarantine. Lsan does none of this.
And if a tool cares then it would also need to intercept
pthread_tryjoin_np and pthread_timedjoin_np, otherwise
it will mess thread states.
Fwiw, asan does not intercept these functions either.

This reverts commit c96d0cceb6.
Causes linker errors which were not fixed by the subsequent commit
either:
/home/nikic/llvm-project/compiler-rt/lib/asan/asan_rtl.cpp:503: error: undefined reference to '__asan::InstallAtExitCheckLeaks()'
Fuchsia's system libraries are instrumented and use the lsan
allocator for internal purposes. So leak checking needs to run
after all atexit hooks and after the system libraries' internal
exit-time hooks. The <zircon/sanitizer.h> hook API calls the
__sanitizer_process_exit_hook function at exactly the right time.
