[Buildroot] [PATCH 07/10] linux: migrate to the kconfig infrastructure

From: Thomas De Schampheleire <thomas.de.schampheleire at gmail.com>
Migrate the linux package to the kconfig infrastructure.
A notable change compared to the original behavior:
- the targets linux-update-(def)config are now always saving the config
file, even for a defconfig bundled in the linux sources. This is done
to keep the kconfig infrastructure simple.
