pahole: Remove --dwarf_offset/-O option 

Too DWARF specific and wasn't working since I implemented type recoding and
removed the Dwarf_Off from struct tag.

To achieve the same result one can use --show_decl_info that also shows the
dwarf offset, since it needs to keep the DWARF specific line number and file
and then use a text editor to find the offset.
