[OE-core] [PATCH 1/1] self-hosted-image: decrease reserved space to 0.5%

[Cui, Dexuan]

Hi Paul,
This reminds me of something slightly similar:
Can we enable the -z option of genext2fs in IMAGE_CMD_ext3()?
For a 40G image, this would save the building host many giga bytes, and make the conversion "from .ext3 to .hdddirect" faster.

Thanks,
-- Dexuan
