[BUG] mac_service with runas specified -> NameError: name '__salt__' is not defined

[lkubb]

Description
Running service.get_enabled runas=user (or any other functions inside that module that expose runas that I tested) on MacOS [Monterey] results in an exception.

Setup
M1 Mac + MacOS Monterey

Steps to Reproduce the behavior

$ sudo /opt/salt/bin/salt-call service.get_enabled runas=username
[ERROR   ] An un-handled exception was caught by salt's global exception handler:
NameError: name '__salt__' is not defined

Expected behavior
Returns a list of launchctl services, including user-specific ones.

Additional context
Related issue: #47705

I already diagnosed it:

• __salt__ needs to be aliased: https://github.com/saltstack/salt/blob/master/salt/utils/mac_utils.py#L41-L44 (see why)
• _run_all_quiet is supposed to not depend on any dunders being initialized, calls _run
• but _run has a special block for runas on MacOS that calls __salt__['user.info']:

  salt/salt/modules/cmdmod.py

  Line 446 in 1671aab

  user_shell = __salt__["user.info"](runas)["shell"]

• possible fix by importing + aliasing the module if __salt__ is not defined or just calling it directly (not sure about side effects currently) or implementing the lookup without reliance on the module

PR incoming. Just need to figure out how to write the test.
