[OE-core] [PATCH 5/5] lib/oe/package.py: is_elf: Make it less prone to false positives

If you are looking at this then you'll want to pull my branch again as I
just pushed a few fixes to make ARM binaries actually work.

Also, a prototype "is this binary stripped" function would be:

elf = oe.elf.Elf.from_file(sys.argv[1])
for h in elf.header.section_headers:
    if h.type == oe.elf.Elf.ShType.progbits and h.name == ".debug_info":
        return False
return True

If you're not working on this yet, please say, as I'll probably have a look
this week.
