[virt-tools-list] [virt-bootstrap] [PATCH v7 11/26] UID/GID mapping: Use empty list instead of None

Resove an issue when only uid_map or only gid_map is specified.

We set the default values to None. However, `len(None)` will raise
an exception. To avoid this we need to set the default values to
[] (empty list).
