Modifying roomservice.py so that it can breakfast for phablet.

These modifications allow the removal of the nexus family from the
main manifest for them to be installed with breakfast as is done
with cyanogenmod.

Additionally, if the device is not on phablet.ubuntu.com, it goes
and fetches the repositories from github/CyanogenMod for easier
bootstrapping.

Adding support to fetch the kernel binary from the Ubuntu archive

Changing the main kernel.mk file to support retrieving, extracting and
using the kernel binary (vmlinuz) provided by the linux-image-(flavour)
package.

If enabled it'll also skip the kernel build and install process,
depending entirely at the kernel provided by the package (only the
headers will be installed at build-time, in case the kernel source
is available).

To enable just change the device specific BoardConfig.mk file, adding
the following:

TARGET_KERNEL_UBUNTU := true
TARGET_KERNEL_UBUNTU_META := linux-image-nexus4
TARGET_KERNEL_UBUNTU_SERIES := raring

Remember that for it to work properly it needs a working package and
respective meta available at the Ubuntu archive.
