kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix race
The new do_bundle_initramfs task introduced in 609d5a9ab9e58bb1c2bcc2145399fbc8b701b85a defeats using the sstate cache. The kernel is resurrected from the sstate cache but ends up being built again since do_bundle_initramfs depends on do_compile. The task is no longer nostamp to avoid causing unnecessary rebuilds. The sstate checksum stamps should know when to rebuild. The task now runs before do_deploy and part of the work has been moved to do_deploy where it now writes to ${DEPLOYDIR} rather than ${DEPLOY_DIR_IMAGE} so that the files end up in sstate. The task can also race against do_install since both call into the kernel build system. This is fixed by making do_bundle_initramfs run after do_install (which therefore also fixes the problem that 3baa63b4d588c3262254528b406ede265dd117bf was addressing.)
