[MANTIC][SRU][PATCH] UBUNTU: [Packaging] Revert arm64 image format to Image.gz

[Dimitri John Ledkov]

The ZBOOT zstd compressed image is not recognised by kexec preventing
kexec load. This is considered release critical functionality.

This option can be attempted to be turned on again, once kexec-tools
are fixed.
