[PATCH v3 09/14] configs: sandbox: activate env in ext4 support

[Patrick Delaunay]

Activate ENV in EXT4 support in sandbox.

The sandbox behavior don't change; the default environment with
the nowhere backend (CONFIG_ENV_IS_NOWHERE)is still used:
the weak function env_get_location() return ENVL_NOWHERE for priority 0.

Changes in v3:
- change env_get_location to avoid gd->env_load_prio modification
