[OE-core] [PATCH] image_types_uboot: remove the middle file

[rongqing.li at windriver.com]

From: Yue Tao <Yue.Tao at windriver.com>

The .gz, .bz2 or .lzma are middle files for making gz.u-boot,
bz2.u-boot, or lzma.u-boot. It should be removed once the final
image is generated. Otherwise, even RM_OLD_IMAGE = 1, it can't
be removed, moreover more and more middle files are genrated via
'bitbake *-image'
