[Bug]: `salt-call --force-color` does not output colors while running in `systemd`

[drlkf]

What happened?

While running salt-call in a systemd service, the --force-color option seems to do nothing:

apt-2 ~ # systemctl cat salt-test
# /etc/systemd/system/salt-test.service
[Service]
Type=oneshot
ExecStart=/usr/bin/salt-call --force-color test.ping

# /etc/systemd/system/service.d/99-failure-report.conf
[Unit]
OnFailure=add-systemd-failure@%n.service
apt-2 ~ # systemctl start salt-test
apt-2 ~ # journalctl -u salt-test | cat -e
