Subject: [rubygems/rubygems] Use OpenSSL constants for error codes.

This fixes the following test error testing against OpenSSL 3.x:

~~~
  2) Failure:
TestGemRequest#test_verify_certificate_extra_message [/builddir/build/BUILD/ruby-3.0.2/test/rubygems/test_gem_request.rb:358]:
<"ERROR:  SSL verification error at depth 0: invalid CA certificate (24)\n" +
"ERROR:  Certificate  is an invalid CA certificate\n"> expected but was
<"ERROR:  SSL verification error at depth 0: invalid CA certificate (79)\n" +
"ERROR:  Certificate  is an invalid CA certificate\n">.
~~~

Where the root cause is this OpenSSL commit:

https://github.com/openssl/openssl/commit/1e41dadfa7b9f792ed0f4714a3d3d36f070cf30e

It seems that OpenSSL upstream considers the constant value just an
implementation detail and therefore this changes the test case to
follow the suite.
