Missing add_crl on X509StoreBuilderRef

[mmastrac]

Example of what I'd like to do:

let crl = openssl::x509::X509Crl::from_der(crl.as_ref())?;
ssl.cert_store_mut()::add_crl(crl)?;

This is the workaround for now:

            extern "C" {
                pub fn X509_STORE_add_crl(
                    store: *mut openssl_sys::X509_STORE,
                    x: *mut openssl_sys::X509_CRL,
                ) -> openssl_sys::c_int;
            }

                let crl = openssl::x509::X509Crl::from_der(crl.as_ref())?;
                let crl_ptr = crl.as_ptr();
                let res = unsafe { X509_STORE_add_crl(ptr, crl_ptr) };
                if res != 1 {
                    return Err(std::io::Error::new(
                        std::io::ErrorKind::Other,
                        "Failed to add CRL to store",
                    )
                    .into());
                }

Looks like #1927 actually contains this fix.
