Revert "Disable ext4 metadata_csum feature when building images"
This reverts commit 4b1db8f892d783dff9b280c965e6ea7bb9d97bd9.
Reason for revert: Devices with 3.8 kernels are now EOL and no images
are built for these devices. All newer kernels support metadata_csum.
BUG=chromium:833643
TEST=none
Original change's description:
> Disable ext4 metadata_csum feature when building images
>
> e2fsprogs v1.44.0+ will enable this feature by default. However, our
> 3.8 kernels (for e.g. falco) cannot mount these images.
>
> BUG=chromium:833643
> TEST=build test image, flash it, check with tune2fs, boot on falco
