binfmt_elf: Dump non-arch notes with strictly matching name and type

Browse source

The note names for some arch-independent coredump notes are specified
manually, albeit by referring to the NN_<foo> #define corresponding
to the NT_<foo> #define that specifies the note type.

Now that there are no exceptional cases, refactor fill_note() to pick
the correct NN_ and NT_ macros implcitly for the requested note type.
