openssl_certificate: Correctly set the version (#30314)

Current openssl_certificate is mistakenly taking its derivating its
version number from the csr version number.

Thos two fields are completly unrelated and hence the version number of
the certificate should be able to be directly specified (via
selfsigned_version parameter).
