[ruby/yaml] Add JRuby-specific warning when psych fails
The error here is confusing for users because JRuby does not use
libyaml and installing it will not help. Instead, JRuby directs
them to a wiki page that describes an issue when multiple
conflicting versions of SnakeYAML are installed.
This change allows us to use the yaml gem and delete our local
sources.
