[Buildroot] [PATCH] support/testing: fix TestExt4 after ext2fs refactoring

[Arnout Vandecappelle (Essensium/Mind)]

Commit bee9e881a2d3addd6880b39f3e33a7180d0b1eb4 removed the
BR2_TARGET_ROOTFS_EXT2_BLOCKS but didn't update TestExt4 that uses
(tests) that option.

Convert it to BR2_TARGET_ROOTFS_EXT2_SIZE, using 16M so the M gets
tested as well.

Fixes: https://gitlab.com/arnout/buildroot/-/jobs/21910153
