scripts/extract-ikconfig: Support LZ4-compressed images.
Support for kernel image LZ4 compression was added around 3.11, but not the corresponding kernel .config extraction. This makes possible extracting the kernel config for LZ4-compressed kernels you're not running, or the current LZ4-compressed kernel if compiled without /proc/config.gz support.
