[Buildroot] [PATCH 13/16 v2] core/show-info: report whether a package is overriden

The show-info output can be used in quite some ways, like to assess the
validity of the current configuration, like a production build in a CI
would do for example. One such assessment would be to ensure that no
package is overriden.

Additionally, when we will (later!) want to check whether we can re-use
cached artefacts of a package, we will not want to do so for packages
that are overridden (nor would we want to actually cache such a result
either).

We do not expose the override location, because this is a purely-local
information, and show info should never contain such local information
(the output of show-info can be shared). Besides, that information is
already known by the user, as they passed it to Buildroot via local.mk
to begin with.
