core_kernel_data(): Fix architectures that do not define _sdata 

Some architectures such as Alpha do not define _sdata but _data:

  kernel/built-in.o: In function `core_kernel_data':
  kernel/extable.c:77: undefined reference to `_sdata'

So expand the scope of the data range to the text addresses too,
this might be more correct anyway because this way we can
cover readonly variables as well.
