Subject: [PATCH 1/2] ci: generalize emulated Linux wheel builds

Turn the current ppc64le build into the sole matrix entry in a new
general build job for all emulated Linux builds, to make supporting
additional architectures easier.

Subject: [PATCH 2/2] ci: add riscv64 wheel builds

RISC-V wheels have been supported by cibuildwheel and PyPI for a while,
so let's build binary wheels for it as many of the boards currently on
the market are rather slow to make building on the spot rather painful.
