linux: add linux-update-config and linux-update-defconfig targets
In analogy to build targets uclibc-update and busybox-update, add extra targets to copy the current configuration to the custom configuration file set in buildroot. These targets facilitate the work of developers adding support for a specific board. linux-update-config copies .config directly. linux-update-defconfig first creates a defconfig and copies that.
