KERNEL_IMAGETYPES lists all the kernel images that we want to build. in cb17b6c2a7 (kernel.bbclass: support kernel image type of vmlinux.gz), some logic was added to support vmlinux.gz which is not a target built by kernel makefiles (only vmlinux). It is clear that the goal of this logic is only to support vmlinux.gz and not others compressed format (such as Image.gz) which are valid target for kernel makefiles.For Image.gz we should rely on the kernel makefiles and not do the compression in kernel class. This patch updates the logic used to filter out non supported kernel target from KERNEL_IMAGETYPES, and make vmlinux.gz a 'special case', instead of *.gz. If more special cases are needed in the future, we could add them in a similar way. This patch should be a no-op for anyone using vmlinux or vmlinux.gz, and on top of that it is fixing the build for Image.gz which was not working until now.

This patch treats 'vmlinux.gz' only as special case, then it looks no problem. Although it might become redundant to add another image type such as 'vmlinux.gz', it's out of scope.
I tried this patch in case of arm, arm64 and x86. I specified the name of compress image for each architecture to KERNEL_IMAGETYPES and I got same images as that compressed by the kernel build system, in particular got Image.gz for arm64 without any errors.
And I added 'vmlinux.gz' to KERNEL_IMAGETYPES and got compressed vmlinux correctly. I think the patch works fine.
