qemu-kvm security and bug fix update

[0.12.1.2-2.415.el6_5.14]

• The commit for zrelease .13 was incomplete; the changes to qemu-kvm.spec
  did not include the ‘%patchNNNN -p1’ lines for patches 4647 through 4655;
  so although the patch files themselves were committed, the srpm build
  did not pick them up. In addition, the commit log did not describe the
  patches.
  This commit corrects these problems and bumps the zrelease to .14.
