internal/trace: end test programs with SIGQUIT

Browse Source 
This change switches from using testenv.Command to
testenv.CommandContext which is a little bit friendlier. It also
switches away from using 'go run' to 'go build' and running the
resulting binary explicitly. This helps eliminate any questions about
signal handling and propagation.

For #72740.
