[PATCH 5/6] lib/layerindex/cooker: Convert string commands to lists where possible

String commands have to be processed by subprocess using shell=True which
is suboptimal for all kinds of reasons, including quoting. Convert to use
a list where possible to improve efficiency and the robustness of code. It
also means copy and paste will be more likely to use the preferred form.
