test 970: verify --write-out '%{json}'

Makes curl_easy_getinfo() of "variable" numerical content instead return
the number set in the env variable `CURL_TIME`.

Makes curl_version() of "variable" textual content. This guarantees a
stable version string which can be tested against. Environment variable
`CURL_VERSION` defines the content.
