tracelib: only consider lib and run dependencies for install and activate
tracelib: only consider lib and run dependencies for install and activate

Without this change, installing from a binary archive fails with trace mode
enabled, because the code will call registry_active on the build dependencies
(which might not be installed, causing the code to throw and the installation
to fail).
