[isar-cip-core][PATCH v4 4/8] swupdate: only check partition uuids on swupdate

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch moves the partition uuid check into a task to only execute
the logic in case an swu image is built. Previously this was checked at
parse time, leading to errors when not setting these variables and
building an image without swupdate support from an layer that also
provides images with swupdate support.
