Please add support for linux/ppc

While binfmt does support ppc64le, it does not support 32-bit powerpc, despite QEMU having an emulator for it. It would be nice to add support for it for projects which want to do CI testing on 32-bit powerpc.

Don't think will do as QEMU 10.2 drops support: https://www.qemu.org/docs/master/about/removed-features.html#bit-ppc-since-10-2
