Munki hangs when caching Apple Softwareupdates

[daniel Shane]

When managedsoftwarecentre cli or GUI checks and downloads software updates from Apple it hangs at downloading. This happens in both the CLI and GUI and appears to be the case if the update is already cached by the OS.

Cli run

`Checking Apple Software Update catalog...

Downloading macOS Monterey 12.1...`

and it just hangs forever Downloading macOS Monterey 12.1...

The GUI hangs at the same Downloading macOS Monterey 12.1...

If software update is run from command line this is the output

softwareupdate-da Software Update Tool Finding available software Downloading macOS Monterey 12.1 Downloaded: macOS Monterev 12.1

and it exits.

Running softwareupdate via ptyexec also exits

sudo /usr/local/munki/ptyexec /usr/sbin/softwareupdate --verbose -d -a Software Update Tool Finding available software Downloading macOS Monterey 12.1 Downloaded: macOS Monterey 12.1

My guess is that no progress of the download in the output results in managedsoftwarecentre hanging.

Happens on macOS 10.15.x, 11.6.x and 12.x
managedsoftwarecentre version 5.6.2.4398
