Add the ops .load for nowhere ENV backend to load the default environment.
This ops is needed for the command 'env load'
Signed-off-by: Patrick Delaunay patrick.delaunay@st.com ---
Changes in v4: - don't use env_import in SPL to avoid to increase its size as it is only required for 'env load' command
Changes in v3: - new: add load ops in nowhere
