lua-shell: Use local pd to store background curtains

Browse source 
This avoids hitting the assert that we don't have any paint nodes in
available when the repaint loop starts.

As we only have just a single curtain, in multi-head/outputs case a new
output creation will destroy the previous curtain and we'll end up
hitting the empty paint nodes assert.

Note that this doesn't add any functionality it just makes sure we're actually
capable of running the lua-shell rather than dying.
