test_thread_join_hang: join leaked inner sleeper (#17068) ...

SleepingUnblockScheduler#unblock deliberately breaks the join path,
so the inner Thread.new{sleep(0.01)} created inside Fiber.schedule
is abandoned mid-sleep when the outer thread exits. It eventually
wakes and lingers in Thread.list, breaking cleanup_threads in later
test files (e.g. test/-ext-/thread/test_instrumentation_api.rb).
Capture the inner thread and join it in an ensure.

     18) Failure:
    TestThreadInstrumentation#test_thread_pass_multi_thread [/build/ruby4.0/test/-ext-/thread/test_instrumentation_api.rb:289]:
    <[#<Thread:0x00007f8dbc9b7f48 run>]> expected but was

     #<Thread:0x00007f8dbc9f45b0 /build/ruby4.0/test/fiber/test_thread.rb:165 sleep>]>.
