Samuel Dionne-Riel 61bdaad9a9 sd-image: Slims the ext4 filesystem even more.
This is to try and squeeze more lost space from the image, so that hydra
starts building it again.

The fsck previous to the resize2fs is required so resize2fs works.

The one afterwards is a sanity check.

Using `-M` from resize2fs will not give much saved space due to a known
(in the manual) issue.
