For #28727
## Details
[This
patch](https://github.com/fleetdm/fleet/commit/866d8bcc0073cf7837d60d43eec0b54ad718375f)
was intended to ensure that Fleet Desktop was always run with the
currently-logged-in user. This patch didn't take Nudge into account, and
it is now causing a command like sudo -u /usr/bin/open /path/to/nudge to
execute, which fails.
This PR fixes the issue by checking whether `opts.user` is populated,
and if not, falling back to the previous behavior for opening apps.
## Testing
I tested that Desktop still opens with this, so it at least doesn't
break that. Discussions ongoing re: how to test Nudge.
For #25924
This PR attempts to fix the issue where the Fleet desktop icon sometimes
fails to appear on MacOS hosts until the hosts are rebooted. Anecdotal
evidence points to this being an issue when system setup is happening,
leading to the theory that Orbit is attempting to launch the app as
`_mbsetupuser` rather than the real logged-in user. The fix here is to
use a different command to get the name of the logged-in user (ignoring
`_mbsetupuser` if it appears), and to launch the desktop app as that
user using `sudo`.
I have tested this on MacOS and Ubuntu hosts, and verified that the
desktop app launches as expected on both.
We don't have a solid reproduction scenario for the issue, but we do
have [some ways to look for relevant
errors](https://github.com/fleetdm/fleet/issues/19172#issuecomment-2627812786),
so we can try this out and see if those errors cease.
this accomplishes two things:
1. We're not waiting on Nudge to exit anymore, preventing issues like
https://github.com/fleetdm/fleet/issues/10044
2. Nudge is launched as a local user instead of root, which is the
recommended way to do it.
