add aarch64 to cibuildwheel for linux
Taking a look to see of a cross-docker build will work. I'll see what I can figure out over in CI runs at https://github.com/altendky/psutil/pull/1.
Draft for:
- [ ] Being more than just an exploration
Well, it builds the wheel but fails the tests. At least some of the failures seem like they are just issues around QEMU which I was using to get aarch64 in the Intel GitHub Actions hosted runners.
FYI the branch used for https://github.com/giampaolo/psutil/pull/2103 (https://github.com/mayeut/psutil/tree/abi3-linux-aarch64) is still active/up-to-date in my fork & all tests requiring skipping with QEMU are marked as such (and some updated for QEMU). If @giampaolo changed its mind wether or not that something he's comfortable to support in the long run (well, the QEMU quirks might be removed once https://github.com/actions/runner-images/issues/5631 lands, but I wouldn't get my hopes up just yet), I can re-open a PR with that.
