tests,json: Remove no longer needed code

* tests/json/t-json.c (parse_version_number, parse_version_string,
compare_versions, check_gpg_version): Remove.
(main): Use have_gpg_version from t-support.h.
--

In the meantime gpgrt provides API for comparing versions (which is
used by have_gpg_version in t-support.h).
