[OE-core] [PATCH 1/2] classes/image_types: add IMAGE_TUNE2FS_ext3

[Paul Eggleton]

Add a variable that allows additional options to be passed to tune2fs,
such as -m to control the amount of space reserved for root.

This could potentially be added for other filesystems, but right now we
need it only for ext3 for self-hosted-image.
