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.
