Add missing musl skip for ppc64le builds (#1109) (#1110)

This commit fixes an issue in the ppc64le wheel builds. One of the two
ppc64le wheel build jobs was incorrectly attempting to build wheels for
musl environments which isn't a supported platform and the jobs failed
to configure. This commit just adds the missing skip for those
environments to the job configuration to fix this issue.
