ci(s390x): sync build-verify (release_version input, host swap, parquet skip, clean checkout)

Bring master's s390x-build-verify in line with the s390x/v0.56.0 branch:
release_version override for clean artifact names, host-swap reuse, parquet test
skip, deb variant usage, and clean checkout to avoid runner disk exhaustion.
