llvm-readobj: add support for printing GNU Notes
Add support for printing the GNU Notes. This allows an easy way to view the
build id for a binary built with the build id. Currently, this only handles the
GNU notes, though it would be easy to extend for other note types (default,
FreeBSD, NetBSD, etc). Only the GNU style is supported currently.
