[Libguestfs] p2v.spec.PL copyright

Hi all, I was adding/correcting some of the copyright and license notices in virt-v2v, and I come across gem-virt-p2v.spec.PL [1] which doesn't have any license; there's only copyright notice. Since I did some modifications there it needs to be corrected. Let's resolve it somehow. yours, - maros [1] - https://git.fedorahosted.org/cgit/virt-v2v.git/tree/rubygem-virt-p2v.spec.PL
