openssl: fix hash

This is the hash for the GitHub snapshot of the 3.4.1 tag, not the
official tarball we're using. When the PR doing this update was
updated after the tarballs came out, updating the hash was forgotten.

I've checked the hashes of the other OpenSSL versions and they're
fine.

Fixes: c05c515eff3c ("openssl_3_4: init at 3.4.1; openssl_3_3: remove")
