Omar Sandoval 28a892ca15 libdrgn: factor out ELF note parsing 
We have a few places where we parse raw ELF notes independently of
libelf, which isn't complicated but also not trivial thanks to alignment
requirements. In preparation for adding another place, factor the
parsing out into a common helper. Also document the complexities around
figuring out the correct alignment.
