The ObjectFileELF parser was not able to load ELF notes from PT_NOTE
program headers. This patch fixes ObjectFileELF::GetUUID() to check the
program header and parse the notes in any PT_NOTE segments. This will
allow memory ELF files to extract the UUID from an in memory image that
has no section headers. Added a test that creates an ELF file, strips
all section headers, and then makes sure that LLDB can see the UUID
value.
