[Buildroot] [git commit] board/qemu/riscv32-virt: convert Linux defconfig into a fragment

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=6939ea5c5d10a280206bd637897d63607d2ef47d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Convert the config to the arch defconfig plus a fragment. When this
fragment is applied we will generate the same config as we previously
did.
