The previous patch introduced the new FOO_KCONFIG_DEFCONFIG variable
to specify a defconfig rule rather than a (def)config file.

Add this to the manual.

Also document the pre-existing FOO_KCONFIG_FILE for which the
explanations were missing altogether.

 In addition to these minimally required lines, several optional variables can
