Should we hold off on this until a matching openssl-sys/openssl has been released?

@djc Fair call. We also would need to evaluate what to do with this comment:

# HACK: Temporarily pinned due to ppc64 ELFv1/v2 ABI issue in 300.5.5, to be
# removed when <https://github.com/openssl/openssl/issues/29815> lands.

... converting to draft now to prevent it being accidentally merged.
