Temporarily disable ppc64le builds for now

We're hitting an issue trying to build on ppc64le:
    https://bugzilla.redhat.com/show_bug.cgi?id=1713090

Temporarily disable it for now. It's important to get this fixed, but I
    don't want to block FCOS work since ppc64le isn't a hard requirement.

Drop `rust_arches` conditional

We no longer care about el7 buildroots. Drop the `rust_arches`
    conditional define since both Fedora and el8 have it defined.
