sysext: fix `--root=` support

when provided `--root=` was failing for `status`:
```
$ systemd-sysext --root=/mnt status
Failed to open '/usr/.systemd-sysext/extensions': No such file or directory
```

path was not relative to the given `--root` - same goes for the `need_reload`
as it was inspired from the `verb_status` section.
