Use git submodule for buildroot (#1445)
* Drop buildroot from git repository

Manage buildroot in a separate git repository and use a git submodule
to include it into the HAOS source tree.

This makes it easier to manage changes to buildroot since it can be
managed by git. A buildroot fork repository is being maintained with
the changes we currently have. It makes the buildroot-patches unnecessary
and should make it easier to rebase and upstream changes to buildroot.

* Remove buildroot-patches

Now that buildroot changes are managed in the buildroot fork repository
there is no need to manage patches in a separate directory.

* Initialize git submodule if necessary

* Move build directory to root

This avoids conflict/local modification issues with the buildroot
git submodule.
