    uboot-config: Fix devtool modify

    Fix a problem with `devtool modify` as suggested by Marcus Flyckt on
    the mailing list:
    ```
        I encountered an issue with `do_config` when using `devtool modify`
        on `u-boot-imx`.

        ```
        [...]
        | cp: cannot stat '[...]/u-boot-imx/2024.04/build/imx8mp_wl400s_defconfig/.config': No such file or directory
        | WARNING: exit code 1 from a shell command.
        ERROR: Task ([...]/sources/poky/../meta-freescale/recipes-bsp/u-boot/u-boot-imx_2024.04.bb:do_configure) failed with exit code '1'
        NOTE: Tasks Summary: Attempted 963 tasks of which 962 didn't need to be rerun and 1 failed.
        Summary: 1 task failed:
          [...]/sources/poky/../meta-freescale/recipes-bsp/u-boot/u-boot-imx_2024.04.bb:do_configure
        Summary: There was 1 ERROR message, returning a non-zero exit code
        ```

        The issue seems to originate from the following lines in
        `workspace/appends/u-boot-imx_2024.04.bbappend`:

        ```
        do_configure:append() {
            if [ ${@oe.types.boolean(d.getVar("KCONFIG_CONFIG_ENABLE_MENUCONFIG"))} = True ]; then
                cp ${KCONFIG_CONFIG_ROOTDIR}/.config ${S}/.config.baseline
                ln -sfT ${KCONFIG_CONFIG_ROOTDIR}/.config ${S}/.config.new
            fi
        }
        ```

        For some reason `KCONFIG_CONFIG_ROOTDIR` does not point to the
        correct directory. It gets its value in `uboot-config.bbclass`:

        ```
        if len(ubootconfig) == 1:
                        d.setVar('KCONFIG_CONFIG_ROOTDIR', os.path.join(d.getVar("B"), d.getVar("UBOOT_MACHINE").strip()))
        ```

        So the main issue is that B gets expanded in this expression, and
        then later B gets changed by `externalsrc.bbclass`.
        `d.getVar("B", False)` does not solve the issue, however the
        proposed change does.
    ```
