Remove memtrace-ko and rd.memdebug=4 support in dracut
    
    This feature could be off loaded to memstrack, which have better
    accurecy, better performance, and have more detailed tracing features.
    
    Also simplify make_trace_mem a bit.
    
    And currently rd.memdebug=4 is unstable, fails from time to time.
