Fixes for scarthgap-dev

Fixes two issues:

• The upstream kernel config fragment for docker has been updated (warning building linux-yocto).

WARNING: linux-yocto-6.6.23+git-r0 do_containers_kernelcfg_check: Kernel Config File docker.cfg may have been overwritten or updated upstream. Ensure no collisions on the following paths: 

/home/adajoh01/code/arm-software/meta-cassini/scarthgap/build/tmp/work/corstone1000_fvp-poky-linux/linux-yocto/6.6.23+git/kernel-meta/cfg/docker.cfg 

/home/adajoh01/code/arm-software/meta-cassini/scarthgap/build/tmp/work/corstone1000_fvp-poky-linux/linux-yocto/6.6.23+git/recipe-sysroot-native/kcfg/cfg/docker.cfg
Or set md5sum to update the checksum.

• Checksum mismatch for greengrass-parsec-plugin (error building greengrass-parsec-plugin)

Note for reviewers: The docker.cfg change only affects the config check - not the kernel config which is actually used.
