dwarf_loader: Print the hexadecimal value for unexpected tags in die__process() 

So that we can get it from user reports, i.e. instead of:

  die__process: DW_TAG_compile_unit, DW_TAG_type_unit or DW_TAG_partial_unit expected got INVALID

We now get:

  die__process: DW_TAG_compile_unit, DW_TAG_type_unit or DW_TAG_partial_unit expected got INVALID (0x4a)

That we can then look in dwarf.h and notice that there is this new:

     DW_TAG_skeleton_unit = 0x4a,

Now lets go support it...
