i386: Put allocated ELF notes in read-only data segment
This changes the i386 linker script and the asm-generic macro it uses so that
ELF note sections with SHF_ALLOC set are linked into the kernel image along
with other read-only data. The PT_NOTE also points to their location.
This paves the way for putting useful build-time information into ELF notes
that can be found easily later in a kernel memory dump.
