meson: Add test dependencies for test_json_parser

This is required to ensure correct test dependencies, previously
the test binaries would not necessarily be built.

The missing dependency was, e.g., visible when doing
ninja clean && ninja meson-test-prereq && m test --no-rebuild --suite setup --suite test_json_parser

Apply this to all branches with meson support, as part of an effort to fix
incorrect test dependencies that can lead to test failures.
