Revert "dcap: Add stubs to build kbs without installing DCAP"

This reverts commit 2b2cc0e.

This commit was found on branches:
remotes/lmilleri/my-rebase,
remotes/redhat/konflux/references/konflux-references,
remotes/redhat/main-archive-2024-09-05,
remotes/redhat/revert-26-my-rebase

But its SHA might have been rewritten after a rebase. Still trackable but
not in the main branch.
