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.
