kconfig/merge_config.sh: Support KCONFIG_CONFIG
All make targets support $KCONFIG_CONFIG because they run scripts/kconf. Make sure merge_config.sh accesses the correct file in all cases. Previously this script broke in two different code paths, one for targets like kvmconfig (which use merge_config.sh -m then call a target that respects KCONFIG_CONFIG) and one for direct use of the script without -m, which called make rules that edit KCONFIG_CONFIG but verified a different file.
