[Buildroot] [git commit] linux: rename config option

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=d8e3e939694c4777c5287e44e67772f4e5c043aa
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Commit a4eef9a3959 (linux: introduce BR2_KERNEL_DTB_KEEP_DIRNAME)
introduced a new config option, but its name was not matching the
naming-scheme of the other config options.

Rename it.

We don't need legacy handling, because that config option was added very
recently and was never part of a release.
