launcher:(script) remove nounset option

[afiune]

Description

When running this script with su we have an error message:

Salims-MBP:~ root# su "$SUDO_USER" /opt/chef-workstation/bin/chef_workstation_app_launcher load
/opt/chef-workstation/bin/chef_workstation_app_launcher:set:20: no such option: u

Removing the -u option seems to work just fine.

Salims-MBP:~ root# su "$SUDO_USER" /opt/chef-workstation/bin/chef_workstation_app_launcher load
Salims-MBP:~ root# su "$SUDO_USER" /opt/chef-workstation/bin/chef_workstation_app_launcher show
