[Buildroot] [git commit branch/2019.05.x] package/mdadm: update website link

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=b96e8be4fd238c340e2ebc002bb6e84236877cce
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.05.x

Neil Brown no longer maintains mdadm. The old website refers to a stale
git repository. There is nothing else but this wiki page to serve as a
website.
