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.
