test: read the WebRTC transport's source as a set of files

Source-reading tests take their text from node_source (node) and node_tree
(hub): webrtc_server.py plus anything under transport/webrtc/, so a check
for something's absence keeps reading the code it guards if that code moves.
test_node_source_scope holds the boundary.
