[BUG] FreeBSD debug output gets merged when using runas

Description
When I use cmd.run 'X' runas=$user -ltrace the command is executed , but additionally the output got some lines from the debug.

Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

Please be as specific as possible and give set-up details.

• on-prem machine
• VM (Virtualbox, KVM, etc. please specify)
• VM running on a cloud service, please be explicit and add details
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit
• jails if it is FreeBSD

Reproduce the reported command with salt-call cmd.run, runas=unbound, and -ltrace on FreeBSD. Start by tracing the cmd.run/cmdmod and direct_call.execute entry points, then inspect the nested.output result shown in the report. Done means command output contains only the pkg results, without trace or debug lines.
