    gdb, btrace: set wait status to ignore if nothing is moving
    
    When record_btrace::wait() is called and no threads are moving, we set the
    wait status to no_resumed.  Change that to ignore.
    
    This helps with enabling per-inferior run-control for the record btrace
    target as it avoids breaking out of do_target_wait() too early with
    no_resumed when there would have been an event on another thread.
