Subject: [PATCH] Simplify pegleg.sh usage

Remove unused code. Set WORKSPACE default to $PWD and set workdir in the
container, so that users of pegleg.sh do not need to have any knowledge of
the internal "/worksapce" mountpath inside the container, and in general
simplify the execution of container command line tools.
