kubuntu-mobile should be built against universe

[Emmet Hikory]

The Kubuntu Mobile project excpects to build against universe. Whilst some pieces have been adjusted to enable this, several steps must be taken to fully accomplish it, as follows:

1: Create a Kubuntu Mobile seed containing only that appropriate for Kubuntu Mobile
2: Create a kubuntu-mobile-meta package referencing the new seed
3: Modify livecd-rootfs to generate kubuntu-mobile images from the metapackage rather than the task
3: Publish a trimmed kubuntu seed that no longer contains kubuntu-mobile
4: Update kubuntu-meta to use the trimmed seed
4: Modify cron.germinate in launchpad to use the new kubuntu-mobile seed to generate tasks
5: Once a kubuntu-mobile task is again available, modify livecd-rootfs to reference the task again

    Order is important, although some parallelisation is available at steps 3 and 4 (as noted in the numbering). Timing is also important: to be complete within maverick, the cron.germinate change must land to launchpad production on 6th September, which means submission to the review process somewhat earlier.

Alternate solution would be to MIR plasma-mobile: bug #626583 tracks this request. The MIR is likely safer, and requires less disruption to the rest of the archive. If applied, the patch in livecd-rootfs 1.148 should be reverted (as it provides no benefit)

Everything here appears to have happened within the natty cycle.
