Add libelf to src/third_party.

Supports a host tool that packs R_ARM_RELATIVE relocations into a more
compact form.


Description:

Library to inspect and manipulate ELF files.

This code is not considered security critical because it is built only for
the host, to support host build tools.  It is not linked into chrome.


Local Modifications:

This is complete elfutils source.  For now we build only libelf.

There are no local code changes.
