	* test/net/http/test_https.rb: Stop the error due to openssl 1.1.1h

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

	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.

[ruby/psych] Fixing compatibility with libyaml 0.2.5

The main issue is that commas aren't allowed in local tags.  libyaml
was updated to follow the spec, and our tests were out of date.

See: https://github.com/yaml/libyaml/issues/196

https://github.com/ruby/psych/commit/3f5e520fd3

Note that this is not security fix, but need for release processs.

	As `RbConfig.expand` modifies the argument and involved `CONFIG`
	values, its values should be mutable.
