Subject: tests/py: Support testing JSON input and output as well

This extends nft-test.py by optional JSON testing capabilities,
activated via '-j'/'--enable-json' parameter).

JSON testing happens for all rules which are supposed to work: After a
rule has been added and the existing tests (payload, ruleset listing
output) have been performed, basically the same test is done again using
a recorded JSON equivalent and (if necessary) a recorded listing output.

The code tries to ease new test case creation overhead by
auto-generating JSON equivalent input via listing the (non-JSON) rule in
JSON format. Also, differing netlink debug and listing output are stored
in *.got files to assist in analyzing/fixing failing test cases.
