Correct spelling of DW_AT_namelist_item

[Alan Modra <amodra@gmail.com>]

This typo was fixed a little while ago in binutils-gdb with commit
e951225303.  I noticed the difference today when importing libiberty
from gcc.  Committed as obvious.

include/
	* dwarf2.def: Correct spelling of DW_AT_namelist_item.
gcc/
	* dwarf2out.cc (gen_namelist_decl): Adjust to suit correct
	spelling of DW_AT_namelist_item.
