feat(tvix/build/protos): add some missing fields r/7265
 - directory in which the castore input nodes are mounted
 - working directory for the build command
 - scratch paths
 - network access y/n
 - whether a (static) /bin/sh should be provided

Populate these fields appropriately, and extend the tests in tvix-glue
with a FOD example.
