fix --format {{json .}} output to match docker

`--format json` should not be the same as `--format {{json .}}`, the
later should actually run through the go template and thus create one
json object per entry instead of an json array.

Includes a vendor of c/common@main since it requires a fix from there as
well.

This matches docker compat.
Fixes #16436
