Subject: [PATCH] build: try to get kernel version from kernel source

When building the kernel modules, try to get the kernel
version from the kernel sources first. This fixes the
kernel modules installation directory if the target kernel
version differs from the host kernel version, like for
CI build or when packaging for linux distributions.
