File add-check-for-tmpfiles-created-at-r.diff of Package rpmlint

Subject: [PATCH] add check for tmpfiles created at runtime

this check parses files in /usr/lib/tmpfiles.d and verifies that
entries that create files or directories are actually listed in
%files.

The check also handles the ghost file check as rpmlint shouldn't
complain about ghost files handled by the tmpfiles mechanism.
