Suppress shell errors in output_env.sh

Browse source 
When the output_env.sh script is executed, if any application wasn't found on
the path by hash, and error was being output, which as an error looked like
the script wasn't working.

This change redirects the output to stderr from hash to /dev/null to suppress
the error.

Also fixes a formatting error.
