[PATCH][live-installer] Detect resume partition and write it to configuration file

["Cody A.W. Somerville" <cody.somerville@canonical.com>]

Hello,

 Please accept this patch which adds live-installer.d/initramfs-tools to the live-installer package. This script (which is based off of code in the base-installer package) will detect the resume partition and write it to the initramfs-tools configuration file at '/etc/initramfs-tools/conf.d/resume'. Basically, it makes hibernation work.

 This patch adds a dependency on di-utils (>=1.68) due to the use of the block-attr wrapper script.

Cheers,
