fix(activate): use exe instead of comm for parent shell detection

Currently, we are using psutil.Process().name(), which includes the
command as entered on the command line. This becomes an issue if the
export script is initiated within another script.

run.sh

    #!/usr/bin/bash
    . ./export.sh

In this case the activate script will see `run.sh` instead of bash.

/proc/<pid>/com vs /proc/<pid>/exe

Use exe(), which contains the full executable path to fix this.
