swupdate: introduce swupdate-ipc to factorize packages

Several tools in SWUpdate was replaced by a single tool (swupdate-ipc).
To avoid breakage, recipe will still build old and new packages. Since
release 2021.11, the swupdate-tools-ipc must be used.

These packages will be removed later:

	swupdate-tools-hawkbit
	swupdate-tools
