Hiroshi SHIBATA 4e225df5ed [ruby/psych] Resolve booleans per YAML 1.2 on the libfyaml backend ...

Scalar type resolution happens in ScalarScanner, not the C backend, so
swapping to libfyaml alone still resolved yes/no/on/off to booleans. Key
the boolean set on Psych::BACKEND so the libyaml default keeps the YAML
1.1 set while the experimental libfyaml backend follows 1.2.
