[PATCH] image.bbclass: Add EXTRA_IMAGEDEPENDS to the do_build task, not do_rootfs

Subject: 

EXTRA_IMAGEDEPENDS is used to ensure things like qemu-native are built and
these are not strictly dependencies of the do_rootfs task. This patch
moves them to the do_build task allowing bitbake a little more flexibility
about when things need to get built by.

I noticed this when qemu-native failed to build and a rootfs was not generated
which is not the intended behaviour.

Also update the syntax to use appendVarFlag instead of get/setVarFlag
