Timeout is defined to 5 seconds in grub-bootdisk-microcode.wks.in and there is no way to easily change it without doing a hack

I am using the Yocto project to build an OS for an intel-corei7-64 machine and I experience that there is a 5 second timeout at the start of boot. I found that if I change the parameter in grub-bootdisk-microcode.wks.in the issue went away. When I tried to apply some sort of patch or some solution to change it I found that wasn't possible or would produce a solution that was not maintainable. There should be a way to override this variable. Either in local.conf or the image file. I am using the Kirkstone branch
