[Error] Failure to create rootful distrobox when using systemd-homed

**Describe the bug**
Users managed by systemd-homed are still not picked up by `distrobox enter --root`

Here is the error on distrobox 2.0.0-rc.4:
```
Error: unable to find user JayB: no matching entries in passwd file
2026/08/05 11:24:23 failed to execute enter command: failed to enter the container: error running the interactive command :exit status 255
```

And on 1.8.2.5:
```
Error: unable to find user JayB: no matching entries in passwd file
```

**To Reproduce**
- Log into a user account managed by systemd-homed
- Create a rootful distrobox
- Attempt to enter it
- An error is returned

**Expected behavior**
After entering the password, I should be presented with a shell in the newly created container. Instead, I get an error.
