Debian 12-compatible minimum openssl crates

Crate `openssl-sys = 0.9.55` seems to look for OpenSSL v1.x, which is
not available to Debian 12. Pinning it up to 0.9.64 makes it match with
OpenSSL 3.x which *is* available.

HOWEVER! Building the crate on Debian 11 works just fine. Pinning the
dependencies this way is an error as I neither use them directly, nor
have any reason to depend on this specific version.

Cargo can't know about the distro version. Maybe I can use crate
features to select different openssl-sys crates? Further work required.
