[OE-core] [PATCH 1/4] image_types.bbclass: set nodesize for btrfs

[Robert Yang]

The default value is 16K which is too big to create image for
core-image-minimal:
rootfs.btrfs is too small to make a usable filesystem
Minimum size for each btrfs device is 41943040.

Use 4K as ext2/3/4 to fix the problem.
