Add ppc64le wheel and binary builds

[imphil]

Build binary wheels for ppc64le, the architecture of "modern" IBM PowerPC machines (i.e., not embedded devices or old Macs, but modern Power servers).

Motivation: We have large compute grids with ppc64le machines and would like prek there.

Testing:

• I did a build dry-run release build in my fork: https://github.com/imphil/prek/actions/runs/36718512604
• I successfully tested the ppc64le wheel that I got out of that pipeline on a POWER9 server with RHEL 8.

Builds in GitHub actions are roughly as fast as the aarch64 builds (5m 40s for linux-ppc64le in my testing vs 5m 42s for linux-arm)
