[Buildroot] [PATCH] support/scripts/pkg-stats: add infra_coinfig to json_output

[Heiko Thiery]

When we use the statistics output to generate a CVE/CPE customer report
showing whether a product is affected by CVEs, we are primarily interested
in whether they are relevant to the target system. Currently we cannot see
if the package is configured for the build (infra==host) and/or the
target system (infra==target).

Therefore, in case of a given configuration, this information is also
stored in the JSON output.
