devtool/standard.py: Allow recipe to disable menuconfig logic

u-boot.inc supports u-boot recipes with or without menuconfig [1].
However, running devtool on a u-boot recipe that does not support menuconfig
results in an error:

cp: cannot stat '/home/r60874/upstream/fsl-xwayland/tmp/work/imx8mmevk-fsl-linux/u-boot-imx/2018.03-r0/u-boot-imx-2018.03//.config': No such file or directory

The problem is the devtool logic assumes that any recipe with a do_menuconfig task
will generate a .config in do_configure().

Fix the problem by removing the assumption with a flag that the recipe can control,
like this:

do_configure() {
    if [ menuconfig-supported ]; then
        ...
    else
        DEVTOOL_DISABLE_MENUCONFIG=true
    fi
}
