wsl.exe always returns 0 exit code

[nzbr]

Bug description

Regardless of the exit code of the command that runs inside WSL, the wsl.exe binary always returns an exit code of 0

To Reproduce

Steps to reproduce the behavior:
Run

wsl.exe -d NixOS false
echo $LASTEXITCODE

Expected behavior

$LASTEXITCODE should be 1

Logs

PS C:\Users\nzbr> wsl -d NixOS false

PS C:\Users\nzbr> echo $LASTEXITCODE
0
PS C:\Users\nzbr> wsl -d Ubuntu false
PS C:\Users\nzbr> echo $LASTEXITCODE
1
PS C:\Users\nzbr>

I verified that it works with Ubuntu, so this is most likely a problem with syschdemd. I haven't tested with the new native systemd feature yet, but I expect that to work

Apparently, we need to switch to systemd-run instead of machinectl in order to get this to work
