Add Elf{32,64}_Nhdr structs with the same member names used by libelf

and glibc.  As noted by guenther@ this is the same layout as our
Elf{32,64}_Note structs and the handful of uses we have in the tree may
switch From _Note to _Nhdr in future.

Prompted by the development version of Mesa using the Nhdr type.
