Update buildroot to 2022.08.1

* Switch to building on BCI instead of Alpine
  Buildroot builds its own toolchain anyway; just bootstrapping that
  toolchain on Alpine required a fair bit of patching. Switching to BCI
  makes this unnecessary.

* Remove unnecessary patches
  A bunch of stuff has since been fixed upstream.

* Update patches to current versions
  Update patches for s390x support to work on the newer buildroot
  release.

* Drop strongswan
  This pulls in a bunch of crypto libs that we don't want to bear the
  burden of updating. It is mostly unused by the community anyway, and
  wireguard is now a much more usable replacement.
