kernel-clk6.18: add ciq-kmod Requires and ship %clk_version macro

Require ciq-kmod from the kernel metapackage so the patched kmod binary
(which handles xz-compressed symvers in CLK 6.x kernels) is pulled in
automatically when the CLK kernel is installed.

Ship /usr/lib/rpm/macros.d/macros.kernel-clk6.18 in kernel-clk6.18-devel
so kmod spec files can use %clk_version to name CLK subpackages without
hardcoding the kernel version string.
