run-tests: added '--json' functionality to store test result in json file

This patch added a new functionality '--json'. While testing, if '--json'
is enabled then test result data gets stored in newly created "report.json"
file in the following format.

testreport ={
    "test-success.t": {
        "result": "success",
        "time": "2.041"
    }
    "test-failure.t": {
        "result": "failure",
        "time": "4.430"
    }
    "test-skip.t": {
        "result": "skip"
            "time": "3.754"
    }
}

Otherwise, if '--json' is enabled but json module was not installed then it
will raise an error "json module not installed".

This "report.json" file will further accessed by html/javascript file for
graph usage.
