    stand/libofw: make OF_hasprop() part of the library
    
    Currently it is only needed by powerpc ofwfdt.c, and defined statically
    there. Make it available as part of libofw, mirroring what we have in
    the kernel.
    
    Two small tweaks are made to the implementation:
      1. Return type is changed to bool
      2. Return 'true' when OF_getproplen() == 0. This matches the expected
         semantics of the kernel version, described in OF_hasprop(9).
