termina_build_image: switch to 4096 block size

This will allow the rootfs image to be placed on block devices with
4096-byte block size (the previous filesystem block size was 1024, which
limits the possible block device block size to <= 1024, 512 in practice).

The initial image size needs to be increased slightly so the test image
will fit - it was already barely fitting into 400 MB, and switching to
4096-byte blocks slightly increases the overhead for small files.

BUG=chromium:942700
TEST=Deploy termina image generated with new script and boot Crostini
