Kernel CI: Fixes for 12.02

[jcrigby 1 Feb 2012] modified the debian/rules so debuild -S builds identical tar files on subsequent builds but recipe builds apparently still produce different tarfiles.
[jcrigby 2 Feb 2012] the problem is the same we have seen before the recipe creates a debian/changelog but the debian/rules clean target overwrites it with one from debian.linaro. This explains the problem we have always had with the kernel recipe version string not working.
[jcrigby 3 Feb 2012] Finished original WIs and discovered a couple more that need to be done.
[jcrigby 15 Feb 2012] Shared header fix has been pushed. The flavour header package for lt kernels
now has all the headers and it no longer depends on the common headers. The kernel-wedge fix for
precise did not work so changing that back to TODO.
[jcrigby 21 Feb 2012] Still need to fix or workaround the kernel-wedge error.
[rsalveti, 22 Feb 2012] John, please create a bug for the kernel-wedge error and close down the blueprint, as the most important WIs are marked as DONE already.
[jcrigby, 22 Feb 2012] Created bug #938907 for the kernel-wedge issue.
