Subject: [PATCH] Deploy and clean rpi-resizerootfs hook and script.

Another way could be to install the Raspberry Pi kernel first, compare
the contents of the initramfses for the Debian and the Raspberry Pi
kernels, and fix the missing files in the latter. Duplicating hook and
script seems a little more straightforward.
