When putting a new module into module cache sysroot folder may contain existing hard link for an existing module with the same name but different build-id. 
Use hard link counter to find out whether anybody else references an old module - if not, we can proceed with deleting unused module directory from $platform/.cache.
Move lock file location to $platform/.lock directory so we can create/delete module's directory while holding a lock.
