Add basic test to persistent environment in ext4: save and load in host ext4 file 'uboot.env'.
On first execution an empty EXT4 file system is created in persistent data dir: env.ext4.img.
Signed-off-by: Patrick Delaunay patrick.delaunay@st.com ---
Changes in v3: - replace specific sandbox command by generic command 'env select' and 'env load' - update after Stephen Warren comments
