Add/rename *-update-config 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.

The original name busybox-update is confusing as it only updates a configuration file.
