On some environments that uses OpenSSL 1.1.1h, the two tests now fail.

```
1) Failure:
TestNetHTTPS#test_get [/data/data/com.termux/files/home/cb/tmp/build/20200924T062352Z/ruby/test/net/http/test_https.rb:47]:
<"0\x82\x03\xED0\x82\x02\xD5\xA0\x03..."> expected but was
<"0\x82\x03\xE30\x82\x02\xCB\xA0\x03...">.
```
Not sure why, but verify_callback now seems to receive only SERVER_CERT
but not CA_CERT.
It would be good to investigate the issue furthermore, but tentatively,
I want to stop the failures.
