[PATCH 08/12] tests: Allow turning on shell tracing from environment variables

[Glenn Washburn]

This allows turning on shell tracing when its not practical or not possible
to use commandline arguments. Turn on tracing when the envvar is an integer
greater than 1, since these can log a lot of messages.
