The test utility takes a numeric parameter from 1 to max tests but this
is off by one to the test case function names. Unify that so it's clear
which test fails.

This is a potentially breaking change to json output. An all zeros uuid
was printed as "-" but we can utilize native json type null for that.
Note the va_copy must be used as va_arg advances the pointer.
{
"nulluuid": null
}

The test cases should be static, otherwise it leads to a warning like
[LD] json-formatter-test
tests/json-formatter-test.c:40:6: warning: no previous prototype for ‘test_simple_empty’ [-Wmissing-prototypes]
40 | void test_simple_empty()

Add formatter type 'str' where the string must be escaped, e.g. paths or
internal data. Otherwise plain %s can be printed if it's known that
there are no special characters.

Add a simple framework to exercise the json formatter and add testing
target that validates the output.
Run 'make test-json' to execute all available tests, requires 'jq'
utility for validation (https://github.com/stedolan/jq).
