tests/shell: add JSON dump files

Generate and add ".json-nft" files. These files contain the output of
`nft -j list ruleset` after the test. Also, "test-wrapper.sh" will
compare the current ruleset against the ".json-nft" files and test them
with "nft -j --check -f $FILE`. These are useful extra tests, that we
almost get for free.

Note that for some JSON dumps, `nft -f --check` fails (or prints
something). For those tests no *.json-nft file is added. The bugs needs
to be fixed first.

An example of such an issue is:

    $ DUMPGEN=all ./tests/shell/run-tests.sh tests/shell/testcases/maps/nat_addr_port

which gives a file "rc-failed-chkdump" with

    Command `./tests/shell/../../src/nft -j --check -f "tests/shell/testcases/maps/dumps/nat_addr_port.json-nft"` failed
    >>>>
    internal:0:0-0: Error: Invalid map type 'ipv4_addr . inet_service'.

    internal:0:0-0: Error: Parsing command array at index 3 failed.

    internal:0:0-0: Error: unqualified type integer specified in map definition. Try "typeof expression" instead of "type datatype".

    <<<<

Tests like "tests/shell/testcases/nft-f/0012different_defines_0" and
"tests/shell/testcases/nft-f/0024priority_0" also don't get a .json-nft
dump yet, because their output is not stable. That needs fixing too.
