  -----------
  [lldb] Fix ThreadList::Update not locking the rhs's mutex

ThreadList::Update is being caught by thread sanitizer. There's even a
comment on the function that both mutexes should be lock (even though
only the "this" mutex was actually being locked). Fix this by locking
both mutexes.
