package/libbson: remove package

The upstream libbson repository has been archived since october 2020,
and there is a known vulnerabilities affecting it (CVE-2025-0755).

Since no other package depends on libbson, and it hasn't seen any recent
activity, let's simply remove it from Buildroot. In case anyone needs a
bson implementation, one could integrate the replacement from mongo-c-driver
instead, see https://github.com/mongodb/mongo-c-driver/tree/master/src/libbson
