Export vold FDE algorithm properties

ro.crypto.fde_algorithm
ro.crypto.fde_sector_size
ro.crypto.volume.contents_mode

These properties were not added to sepolicy export2vold. vold can't access
crypto algorithm type when flashing a GSI image and when the properties are in
/vendor/build.prop. This prevents FDE from working.
