    Fix oidc-auth cli for python3

    The response to oidc token request is bytes type. This is
    fine with python2 as there is no distinguish between bytes
    and string. But in python3, bytes and string are different,
    causing some string operations (such as split(response, "\n"))
    to fail. This is fixed by converting the bytes into string if
    the script is run in python3.

    Test Plan for Debian and CentOS:
    PASS: python3-oidcauthtools package build.
    PASS: With oidc-auth-apps applied and configured, run oidc-auth
          cli to get a token.
