Elfutils license change

[Elena Zannoni]

The Elfutils package license has been changed from OSL to
GPL+exceptions.  Elfutils is now also under the umbrella of the OIN
(http://www.openinventionnetwork.com). A new elfutils package with
this license is available in the Fedora development stream, and will
make its way in the next round of RHEL updates, as well as being
bundled with Systemtap in said updates.
