kmod_config: fix kcmd line parser with dots after =

Check if '=' appeared before the dot. In this case, it's not a valid
module option in kernel command line.

The command line that was failing is:

"root=/dev/sda3 ro pcie_aspm=force init=/sbin/bootchartd
	initrd=../initramfs-linux.img BOOT_IMAGE=../vmlinuz-linux"
