Before making / mutable/immutable, podman-machine checks if the mount is
being done in /home or /mnt. However the current check is always going
to be true:
```
!strings.HasPrefix(mount.Target, "/home") || !strings.HasPrefix(mount.Target, "/mnt")
```
is false when mount.Target starts with "/home" and mount.Target starts
with "/mnt", which cannot happen at the same time.
The correct check is:
```
!strings.HasPrefix(mount.Target, "/home") && !strings.HasPrefix(mount.Target, "/mnt")
```
which can also be written as:
```
!(strings.HasPrefix(mount.Target, "/home") || strings.HasPrefix(mount.Target, "/mnt"))
```
The impact is not too bad, it results in extra 'chattr -i' calls which
should be unneeded.
