cml1: use KCONFIG_CONFIG_ROOTDIR in savedefconfig

When running do_savedefconfig with a KCONFIG_CONFIG_ROOTDIR other than
B, this task runs oe_runmake in a directory different from the other
config-related tasks.

For example, in U-Boot with the new configuration flow from wrynose and
configs defined using the UBOOT_CONFIG_* variables, the project sources
and configs will be located in a subdirectory of ${B}. This will result
in the following error when running do_savedefconfig:
make: *** No rule to make target 'savedefconfig'.  Stop.

Fix the do_savedefconfig task so it runs in KCONFIG_CONFIG_ROOTDIR.
