3.13 DKMS package review

[Andy Whitcroft]

tl;dr I have been reviewing the automated DKMS package testing.  After
fixing a couple of the packages I believe we are now in a position to
call v3.13 good enough for the main archive.

The DKMS testing for the trusty release pocket kernel (v3.12) shows the
following failures:

    FailedBuild openswan_modules_dkms
    FailedBuild open_vm_tools_dkms
    FailedBuild oss4_dkms
    FailedBuild pvcam_dkms
    FailedBuild r8168_dkms
    FailedBuild speakup

The equivalent testing for the CKT PPA trusty kernel (v3.13) shows the
following failures:

    FailedBuild openswan_modules_dkms
    FailedBuild open_vm_tools_dkms
    FailedBuild openvswitch_datapath_dkms
    FailedBuild oss4_dkms
    FailedBuild pvcam_dkms
    FailedBuild r8168_dkms
    FailedBuild speakup

The only additional failure is openvswitch_datapath, the changes here
are currently being worked with upstream but I have confirmed with the
server team that they are not relying on any of the additional features.

I personally have been running these kernels on various kit here without
incident.  I therefore propose we can release the v3.13 kernel out of the
PPA into the archive.
