Roger Pau Monné 881c145431 elfnote: place note in a PT_NOTE program header 
Some tools (firecraker loader) only check for notes in PT_NOTE program
headers, so make sure the notes added using the ELFNOTE macro end up
in such header.

Output from readelf -Wl for and amd64 kernel after the change:

Elf file type is EXEC (Executable file)
Entry point 0xffffffff8038a000
There are 11 program headers, starting at offset 64
