[UNSTABLE][IMPISH][PATCH] UBUNTU: [Config] enforce ZSTD compression

BugLink: https://bugs.launchpad.net/bugs/1931725

Previously v5.13+ based kernels enabled ZSTD kernel image compression
on amd64 & s390x. Due to significant bootspeed impact this change
should be enforced for all derivatives as well. Not all derivatives
currently inherit and enforce all annotations from parent config.

Fixes: f88bdfaeaf ("UBUNTU: [Packaging] use ZSTD to compress s390 kernels")
